Lous Does Truck Manifolds

We do truck exhaust manifolds at the 4 Lou's Muffler and Brake (a division of Lou's Custom Exhaust) locations in Hyannis, Plymouth, Quincy, and Westport.   With winter coming, now is the perfect time to get that plow truck or your daily driver's manifold fixed!   Those manifold leaks will make you lose a lot of low end power, gas mileage, and can let the bad exhaust fumes into your cabin!  

At Lou's Muffler and Brake our manifold prices are competitive with, or below, the competition's prices.  We will also price match any written estimate.   When we do a manifold we extract all the old studs, even if the threads are still good.  We replace them with factory, stainless, studs and nuts. We also get the factory, metal, gasket instead of using the supplied fiber one.    

Most manifold jobs have a same day turnaround and, as with all of our work, we give a 2 year warranty on parts and labor.  

Give us a call or swing by any one of our 4 locations for a free estimate on your manifold needs!

Is Your Car Winter Ready?

Is your Car Ready For the Winter? 
 

 With the winter season quickly approaching the time to get your vehicle ready for the cold months will be upon us before we know it. With every vehicle there are numerous things to keep in mind when winterizing, such as your exhaust, brakes, battery, tires, cooling system, and oil. With that in mind, here's some advice on what to think about when you're getting your car ready for another season of cold. 
 
Brakes:
 
A VERY important item for the winter. If your brakes are wearing out parts of your ABS (anti-lock braking) system may not be working properly. This can cause dangerous conditions in the snow. We do free brake estimates at Lou's so we are the best place to come to find out if you need work or not. Our repair prices are highly competetive on braking systems 
 
Exhaust:
 
I know some of you are reading this and saying "What does my exhaust have to do with driving in the winter?" Normally the exhaust isn't an issue but if for some reason you get stranded out in the cold and the snow with only your car to keep you warm an exhaust leak will all of a sudden become very noticeable. You don't want to be in a bad situation and not be able to run your car for heat due to an exhaust leak so come on in to any Lou's location for a free exhaust inspection. 
 
Tires: 
 
As the only part of your car that actually touches the road, making sure that your tires are ready for the winter season is probably the first and most important thing to take into account when winterizing your vehicle. While making sure that your tires are rotated and aligned is important, checking the tread on your tires is probably the first thing that should be checked on your new and used cars. 
 
If getting your car to your local car dealership isn't a viable option, then an easy way to check the tread on your tires is to take a penny and insert it into the most worn section of your tired tread. If you are able to see Mr. Lincoln's head, then it's time to get your tires replaced, preferably before there's snow on the ground. Depending on the region you live in, then checking the tread on your tires might not be enough, and you may need snow tires to make it through the winter. Figure out which option will best suit your needs and make sure that you have everything taken care of before the first flakes of snow fall. 
 
Getting your tires checked out is easily the simplest and most important thing you can do to make sure that your care is ready for the winter season...but it's not the only thing.

At Lou's we can check your tread, check your tire pressures, rotate your tires, and check your braking system too. 
 
Cooling System: 
 
Ok, with winter on its way it seems counter-productive to be thinking of your cooling system, but your cooling system is also what houses your anti-freeze, which is very important to making it through this winter. While you should change out the anti-freeze in your car every two years, it's always a good idea to have it checked before the start of every winter. Swinging by any Lou's Custom Exhaust location is a quick way to have your anti-freeze levels checked and make sure that you won't have to worry about your car freezing up. 
 
With having your anti-freeze checked, it's not a bad idea to pour one of many anti-freezing chemicals that are designed for your fuel lines. This can help to prevent any moisture that's in your fuel line from freezing up and preventing your car from starting or damaging the fuel lines which can add up to costly repairs. 
 
Battery:
 
Make sure that your battery's terminals are clean and tight, ensuring a good connection for your electrical systems. Getting the charge checked on your battery before the bad weather hits is a good way to make sure that you won't have to have your care jumped in three feet of snow. 
 
We can clean your terminals at Lou's and get replacement batteries for you if your battery has been getting weak. 
 
Heater and Defroster:
 
Make sure that your heater and defroster work before the winter hits. Not only is this important for your own comfort inside of the car, but it's important for ensuring that you'll have good visibility through your windows. 
 
Emergency Kit:
 
If you don't already have an emergency bad weather kit in your car, now is a good time to make one. A warm blanket, jumper cables, an ice scraper, de-icer, rock salt or sand, a tire inflator, a flashlight, and a few snacks are essential parts to any snow emergency kit. If you already have one, check to make sure that everything in there is still in good shape and easily accessible. If for some reason you do have car troubles and are stranded you'll want these things to help make it until help arrives. 
 
Getting your car ready for the winter season doesn't have to take long, but not getting it done can cost you a lot of money when you have to get these things repaired in the middle of the winter season or when you're forced to buy a new car after your current vehicle is damaged beyond repair. Save yourself some time, money, and protect your safety by getting your car checked out for free at Lou’s and ready for the winter season as soon as possible.

We Do Brakes!

We do free brake inspections at all 4 of our locations (Hyannis, Plymouth, Quincy, and Westport). Routine inspections keep your vehicle stopping safer, longer. How often you have to change your brakes depends on a lot of things driving conditions, rotor thickness, quality of brake pads, and more. A routine brake inspection makes certain that your braking system is safe.

Our hours are Monday - Saturday from 8:30am-5:30pm.  Swing by anytime and our professional technicians will visually assess your brakes to determine if any service or repairs are needed.

A few signs your brakes might need service or replacement:

  • Brake pedal is low or spongy (goes to the floor when pressed)
  • Brake pedal is hard to depress (won’t go down at all)
  • Brake service warning light stays lit at all times
  • Squealing or grinding at stop

If you are experiencing any of these symptoms please bring your vehicle in for a free brake inspection. If our technicians find your brakes need attention we can usually fix it the same day!

Mig Welding Exhausts


Mig Welding 
 


 


 
A Mig (metal inert gas) welder is an automatic wire-fed welder setup that arcs a wire compound to fuse metals together via electricity, which heats up the compound and melts it. This setup allows a much faster, easier way to repair exhausts on vehicles which makes it more convenient for the customer. 
 
At Lou’s we pride ourselves on quick service, which means having the right tools for the job. With up to three Mig setups per shop, run by experienced welders, they can very quickly repair and replace just about anything on the exhaust. 
  

Upon finishing up a welded system, the welds are all checked for any tiny leaks that might have been missed and sealed up completely to insure it’s 100% airtight.  We use a modified stethoscope to listen for leaks.

Sometimes, even small cracks in the exhaust can be welded and sealed, without having to replace the actual pipe and sometimes small sections that are bad can be cut out, welding into the good sections.   The welder lets us keep your repair prices down.

Come down to Lou’s Muffler and Brake of Hyannis, Plymouth, Quincy, and Westport today, and get your free on-lift estimate!  You never know, that repair might not be as expensive as you anticipate!

Flowmaster Mufflers

Flowmaster Mufflers

Looking to get an aggressive muscle car sound from your car or truck? Look no further than the king of loud, Flowmaster mufflers! Flowmaster mufflers got their start in the racing scene and have been around for  over 30 years.
  
Flowmaster mufflers are a chambered muffler and can range from mild to wild for whichever application you may need! The most popular is the 40 series muffler which is a dual chambered muffler that provides an aggressive sound. Our shops only stock the 409 stainless steel Flowmasters as opposed to the aluminized steel Flowmasters that almost all other shops use. The technology designed by the exhaust scientists at Flowmaster is called the “power chamber” which is a chamber that creates a negative pressure that is used to increase horsepower, torque, and fuel mileage. These mufflers also use baffles to separate and recombine sound and pressure waves for an aggressive exhaust note. 

Flowmaster, by many, is considered to be the original performance muffler and is often used by owners of classic cars, hot rods, firebirds and mustangs to name a few. What if you don’t have a muscle car or a hot road and you have a truck? Good news! Flowmaster also makes mufflers for applications on trucks! The very popular 40 series muffler that produces an aggressive tone and the somewhat quieter 50 series are available in a single inlet and single outlet design to be used with your factory exhaust or for most truck owners that want that dual exhaust they offer single inlet dual outlet design. Using the dual outlet version of either muffler allows us the ability to build you your dual exhaust system however you want it. But what if the 40 series isn't loud enough for you? Well you've got good news again! For those who want their vehicle loud and proud and to set off car alarms the offer a single chamber 10 series!
 
If you like that classic muscle car sound or an aggressive exhaust note Flowmaster is for you and available for installation at Lou’s Muffler and Brake of Hyannis, Plymouth, Quincy, and Westport!

Is Your Car Ready To Go Back To School?

How Can I Be Sure My Car, or My Child's Car is Ready For the School Year?


School season is back! Its time to start thinking about if your car, or your child's car, is ready for the school year before they go! But how do you know if your car is ready? Easy, bring it to us at Lou’s for a free inspection and readiness check! 
 
What is involved? 
 
With every vehicle there are numerous things to keep in mind when inspecting, such as your exhaust, brakes, battery, tires, cooling system, and oil. With that in mind, here's some advice on what to think about when you're getting your car ready for another season of cold. 
 
Brakes 
 
A VERY important item for any season and any car. If your brakes are wearing out parts of your ABS (anti-lock braking) system may not be working properly. This can cause dangerous conditions in the snow. We do free brake estimates at Lou's so we are the best place to come to find out if you need work or not. Our repair prices are highly competetive on braking systems 
 
Exhaust 
 
I know some of you are reading this and saying "What does my exhaust have to do with being safe going back to school?" Normally the exhaust isn't an issue.  However, if for some reason you get stranded out in the cold and the snow with only your car to keep you warm an exhaust leak will all of a sudden become very noticeable. You don't want to be in a bad situation and not be able to run your car for heat due to an exhaust leak so come on in to any Lou's location for a free exhaust inspection. 
 
Tires 
 
As the only part of your car that actually touches the road, making sure that your tires are good is probably the first and most important thing to take into account when inspecting your vehicle. While making sure that your tires are rotated and aligned is important, checking the tread on your tires is probably the first thing that should be checked on your new and used cars. 
 
If getting your car to your local Lou's isn't a viable option, then an easy way to check the tread on your tires is to take a penny and insert it into the most worn section of your tired tread. If you are able to see Mr. Lincoln's head, then it's time to get your tires replaced, preferably before there's snow on the ground. Depending on the region you live in, then checking the tread on your tires might not be enough, and you may need snow tires to make it through the winter. Figure out which option will best suit your needs and make sure that you have everything taken care of before the first flakes of snow fall. 
 
At Lou's we can check your tread, check your tire pressures, rotate your tires, and check your braking system too. We have local shops whom install tires if we find you should do so! 
 
Cooling System 
 
We know that with winter on its way it seems counter-productive to be thinking of your cooling system, but your cooling system is also what houses your anti-freeze, which is very important to making it through this winter. While you should change out the anti-freeze in your car every two years, it's always a good idea to have it checked before the start of every winter. Swinging by any Lou's Custom Exhaust location is a quick way to have your anti-freeze levels checked and make sure that you won't have to worry about your car freezing up. 
 
Things to check are fluid level, condition, and mixutre of water/coolant. Too much water in the water/coolant ratio could cause freezing and internal engine damage! 
 
With having your anti-freeze checked, it's not a bad idea to pour one of many anti-freezing chemicals that are designed for your fuel lines. This can help to prevent any moisture that's in your fuel line from freezing up and preventing your car from starting or damaging the fuel lines which can add up to costly repairs. 
 
Battery 
 
Make sure that your battery's terminals are clean and tight, ensuring a good connection for your electrical systems. Getting the charge checked on your battery before going off to school is a good way to make sure that you won't have to have your care jumped at the worst time. 
 
We can clean your terminals at Lou's and get replacement batteries for you if your battery has been getting weak. 
 
Heater and Defroster 
 
Make sure that your heater and defroster work before heading off to school for the winters. Not only is this important for your own comfort inside of the car, but it's important for ensuring that you'll have good visibility through your windows. 
 
Emergency Kit 
 
If you don't already have an emergency kit in your car, now is a good time to make one or buy one. A warm blanket, jumper cables, an ice scraper, de-icer, rock salt or sand, a tire inflator, a flashlight, and a few snacks are essential parts to any snow emergency kit. If you already have one, check to make sure that everything in there is still in good shape and easily accessible. If for some reason you do have car troubles and are stranded you'll want these things to help make it until help arrives.


Getting your car ready for the school season doesn't have to take long, but not getting it done can cost you a lot of money and stress when you have to get these things repaired in the middle of the winter season. Save yourself some time, money, and protect your safety by coming to one of our locations to get your car checked out and ready for the winter season as soon as possible!

Saving Customers Money With Custom Bent Piping

Repair chains and auto dealerships buy all their exhaust parts from other companies that make the parts for them. At Lou’s Muffler and Brake, a division of Lou's Custom Exhaust, we get all our piping in unbent, 10 foot, sticks of 14 gauge pipe (Most aftermarket companies use much thinner 18 or 16 gauge pipe). Our bending machine uses a smooth die bending shoe instead of a “crimp” style one which helps keep the exhaust flowing smoothly.  We then use our bending machine to custom fabricate the system that will fit onto your vehicle. By doing so we greatly reduce the cost of the parts and as a result the cost for the repair. 

Our hydraulic pipe benders use an electic motor that is controlled by a double acting lever allowing us to extend and retract a hydraulic cylinder that moves one of the 3 bending shoes. We have a variety of pipe bending shoes ranging from 1.5” pipe all the way up to 3” pipe. We have a matching shoe for each size diameter of pipe in between those sizes as well.

Generally the pipe fits inside the curved crescent shape of the bending shoe. This ensures that when the pipe is being bent it will not slip from the metal shoe. Various pegs are arranged in such a way that as the cylinder extends the pipe shoe, the pipe is forced against the metal pegs as a hold stop on either side of the bending center of the pipe. In other words, as the hydraulic bending cylinder pushes the pipe that is supported by the shoe, the hold pegs stop the pipe from moving so the pipe can be bent in the center of the cured shoe form. Our pipe benders use a dial that we can set to determine the angle of the bend. 
 
So if you’re looking for a high quality, inexpensive, smooth flowing custom or replacement system remember Lou's of Hyannis, Plymouth, Quincy and Westport are the place to go.

Lou's Custom Exhaust Stocks and Installs S&B Cold Air Intakes

We stock and install S & B cold air intakes in our shops.   S & B filters come with a 1 million mile warranty and are designed to work with your vehicles existing ECU tuning.   https://www.sbfilters.com/demandbetter

What is a cold air intake and how does it work?

 

                                                                                             

The main purpose of a cold air intake system is to draw in more “cold air” using a better flowing filter and a shorter intake tube into the vehicles intake. The colder air has a higher density than warm air (which is used by your factory airbox) and creates an increase in performance and efficiency. 
 
The Removal of your stock intake system will also remove any resonator or baffle boxes that slow the air down and the new performance intake will be allowed to flow freely and you will also notice it sucking in more air by a whooshing sound created from the air being drawn in. A typical installation of a cold air intake take around 60 minutes from removal of the factory intake system to completion of your new cold-air system.

   

Here at Lou’s Muffler and Brake of Hyannis, Plymouth, Quincy, and Westport we source and install air intakes from any company including S&B, Airaid, and K&N.

We Do Quiet Mufflers Also!


We replace stock mufflers too!

Every vehicle is fitted from the factory with a muffler. The main purpose of the muffler is to keep the vehicles exhaust note to a minimum by using a series of internal baffles and chambers that are specially designed to reduce the loudness of the exhaust sound pressure. 


Just because our name has custom in it does not mean we won't make your exhaust quieter instead of louder.  In fact our ability to custom create a quiet, factory style, exhaust can save you hundreds over going to a chain with pre-bent piping or even more if you look to the dealership for a replacement.

We can even get higher quality, stainless, aftermarket mufflers for your vehicle.  They are a special order item but we can usually source them in a few days. 

All of our shops offer a wide variety of replacement mufflers. It doesnt matter if you drive a hybrid, car, truck, suv, box truck, or even a tow along generator!    We have what you need so come see the exhaust experts at Lou’s Muffler and Brake in Hyannis, Plymouth, Quincy, and Westport!

Why Use Borla Exhaust?

 

Why Is A Borla Exhaust A Good Option?

 
Borla uses aircraft quality T-304 stainless steel on all of there products so you will never need another replacement! 304 stainless steel is the not commonly used for automotive exhausts and it is a high quality stainless steel, is non magnetic, does not get surface rusting like 409 stainless, and can also resist corrosion much better than regular steel. This type of stainless also has a low electrical conductivity rating and a low thermal conductivity rating. Below you can see the difference in materials between a Borla muffler and a stock replacement type muffler that is not made of stainless steel.

Borla's street mufflers use the same technology as their race mufflers offering a high flow straight through design which offers increased horsepower and torque gains from 7-10% and increased fuel economy in normal driving conditions. Because of this design these mufflers also feature less interior noise (resonance) than that of a Flowmaster that uses baffle technology. The sound created by the Borla muffler is a deep mellow tone.

 Based on the technology used to design these mufflers you don't need to use a larger diameter exhaust system to get a louder exhaust this will actually have a reverse effect when using the Borlas. If you were to install a larger pipe size with Borla mufflers you will create the interior drone that these mufflers are designed to lower by the exhaust gasses “bottling up” inside the muffler instead of flowing freely through to the tailpipe to exit quicker. So, if you're looking for the industries “Most Winning Exhaust” on your track or street car swing on by one of our shops in Hyannis, Plymouth, Quincy, and Westport and get the muffler that outlasts the competition and doesn’t need to be replaced!

Catalytic Converters

Are you noticing a sulfur type odor coming from your exhaust? It could be your catalytic converter!


The catalytic converter is a passive device installed on your exhaust system by the factory that is designed to reduce your car’s emissions levels. The converter contains platinum, palladium, and rhodium which are used to clean the exhaust gases by a chemical reaction which in turn reduces the toxic gases to less harmful ones. 

 
A damaged or clogged converter can cause your check engine light to illuminate and in some cases you may notice an odor similar to rotten eggs. There are also many different ways a converter can fail such as: converter fracture, overheating, converter meltdown(pictured below), and heavy carbon deposits.   Here is a great video that explains why a converter fails https://www.youtube.com/watch?v=VbDlSNYC7tM

You may want to try an easy solution to fixing a converter before replacing it and there is one product you could try which is called Cataclean.Cataclean is a product that is cleans your fuel system and can lower your emissions. If you wish to try this approach feel free and if it doesn't do the trick come down to Lou’s Muffler and Brake, a division of Custom Exhaust, in Hyannis Plymouth, Quincy, and Westport we offer free check engine light scans to help you determine if your catalytic is not functioning properly and we have to ability to replace the converter for less than the dealer if needed. Come on in and have the code scanned for free!

Why Install a Dual Exhaust?

Dual exhausts can be applied to many vehicles that don’t come dual from the factory.  Some vehicles also come with a factory dual exhaust but many times it is too quiet due to stock, restrictive, mufflers.  Dual exhausts can be run on almost every single pickup truck and many cars and SUV’s. People pick a performance style dual exhaust for 3 reasons. 

1) A performance dual exhaust has a great sound to it. If you are a person who is into the sound of performance exhausts you know exactly what we mean. If you are curious head on over to your youtube page and check out some sound clips. 
 
2) A performance dual exhaust, when driven gently, will actually increase your overall fuel mileage. 
 
3) A performance dual exhaust, last but not least, also gives you a horsepower/torque gain from your motor. 
 
Lou’s Custom Exhaust carries only high quality material, from a line of popular stainless performance mufflers, polished stainless tips, and thick, 14 gauge aluminized and stainless steel tubing. 
 
Typically the job itself ideally requires about two hours to complete. All the pipe is bent in the shop, and fully welded and checked for leaks. The tips can be picked from a variety along the wall in each shop showroom, and a choice between three different brand mufflers as well.

Call or stop by for a free estimate and go for a Dual Exhaust today!

MIG Welding

A Mig (metal inert gas) welder is an automatic wire-fed welder setup that arcs a wire compound to fuse metals together via electricity.  The electricity heats up the wire compound and melts it. This setup allows a much faster, easier way to repair exhausts on vehicles which makes it more convenient for the customer.

At Lou’s we pride ourselves on quick service, which means having the right tools for the job. With up to three Mig Welders per shop, run by experienced welders, we can very quickly repair and replace just about anything on the exhaust.

Upon finishing up a welded system, the welds are all checked for any tiny leaks that might have been missed and sealed up completely to insure it’s 100% airtight.  We use a modified stethoscope to listen for leaks. 

Sometimes, even small cracks in the exhaust can be welded and sealed, without having to replace the actual pipe and sometimes small sections that are bad can be cut out, welding into the good sections.   The welder lets us keep your repair prices down.

Come down to Lou’s Muffler and Brake of Hyannis, Plymouth, Quincy, and Westport today, and get your free on-lift estimate!  You never know, that repair might not be as expensive as you anticipate!

Free Check Engine Light Diagnostics

Free Check Engine Light Diagnostics Including Video

Since 1995, all vehicles have been equipped with an OBDII port, in which you can use a scan tool/code reader to see what is wrong with your vehicle. The ECU or Computer in your vehicle is actually receiving data from a variety of different sensors to make sure everything is working properly and in sync. We also have a video on youtube if you want to see a quick example.

Even if the code may not be exhaust related, Lou’s Custom Exhaust can still scan the computer’s codes on your vehicle free of charge and quickly.

The most common codes seen are the catalytic converter low efficiency (P0420), Oxygen Sensor codes, and EVAP codes (Leak in the evaporative emissions system).  Once the problem is fixed, the code can then be erased.  

If you are getting the problem fixed to shut the light off for a state inspection you will have to drive about 100 miles.   This is because it takes about 100 miles for the car's computer to recognize the problem is fixed and change its status from "Not Ready (code manually cleared)" to "Ready".    This is something that is key for Massachusetts annual vehicle inspections.   

So if you are having trouble swing on by our Hyannis, Plymouth, Quincy, or Westport shop and we can let you know what is going on!

How Does Our Custom Exhaust Bending Save you Money?

Repair chains and auto dealerships buy all their exhaust parts from external companies which make the parts for them. At Lous Muffler and Brake of Hyannis, Plymouth, Quincy, and Westport we get all of our piping in unbent, 10 foot, sticks. We then use our bending machine to custom fabricate the system that will fit onto your vehicle. By doing so we greatly reduce the cost of the parts and as a result the cost to the customer for the repair.  We can also avoid some factory weaknesses that caused your exhaust to break in the first place. 



How does the bending machine work?


Our hydraulic pipe benders use an electric motor that is controlled by a double acting lever allowing us to extend and retract a hydraulic cylinder that moves one of the 3 bending shoes. We have a variety of pipe bending shoes ranging from 1.5” pipe all the way up to 3” pipe. We have a matching shoe for each size diameter of pipe in between those sizes as well. 

Generally the pipe fits inside the curved crescent shape of the bending shoe. This ensures that when the pipe is being bent it will not slip from the metal shoe. Various pegs are arranged in such a way that as the cylinder extends the pipe shoe, the pipe is forced against the metal pegs as a hold stop on either side of the bending center of the pipe. In other words, as the hydraulic bending cylinder pushes the pipe that is supported by the shoe, the hold pegs stop the pipe from moving so the pipe can be bent in the center of the cured shoe form. Our pipe benders use a dial that we can set to determine the angle of the bend.  Our bending machine also uses a smooth die bending shoe instead of a “crimp” style one.

So if you’re looking for a high quality, inexpensive, smooth flowing custom or replacement system remember Lou's Muffler and Brake of Hyannis, Quincy, Plymouth, and Westport are the place to go.

What does an oxygen sensor do?

What Is An Oxygen Sensor? What Does It Do?


Oxygen Sensors, commonly referred to as O2 sensors, are part of your vehicles emission system. The purpose of the downstream, after converter, sensors is to monitor the quantities of harmful exhaust gases flowing into and out of the catalytic converter to ensure the converter is working properly.The sensor does not actually measure the amount of oxygen, but rather the difference between the amount of oxygen in the exhaust gas and the amount of oxygen in air.  There is also the upstream oxygen sensor which monitors the exhaust gasses to help the computer adjust your fuel/air ratio for maximum gas mileage and power.

Rich mixture (too much fuel) causes the sensors to demand oxygen. The demand for oxygen causes the internal circuit of the oxygen sensor to build voltage. Lean mixture (not enough fuel) causes low voltage. Modifying the signal that the oxygen sensor sends to the engine computer can damage the vehicle not to mention is extremely illegal and carries a hefty fine. When the engine is under a lower load such as slowing accelerating , or maintaining a constant speed, it is operating in closed loop mode.While in this mode your vehicles computer is basically anticipating your next move, assuming that you will be accelerating or decelerating . This loop forces the engine to operate both slightly lean and slightly rich. As the computer attempts to maintain a happy medium, If computer modifications have been done to the engine forcing it to run moderately lean, there will be a slight increase in fuel economy, usually at the expense of emissions, much higher exhaust gas temperatures, and an increase in power that can quickly turn into misfires and a drastic loss of power, as well as potential engine damage, at extremely lean air to fuel ratios.

If modifications cause the engine to run rich, there will be a slight increase in power to a point (the engine starts flooding from too much unburnt fuel) but at the cost of decreased fuel economy, and an increase in unburnt hydrocarbons in the exhaust which will basically turn your catalytic converters into a small furnace. Prolonged operation at rich mixtures can cause catastrophic failure of the catalytic converter. The ecu also controls the spark engine timing along with fuel injector pulse, so modifications which alter the engine to operate either too lean or too rich may also result in inefficient fuel consumption whenever fuel is ignited too soon or too late in the combustion cycle. A faulty O2 sensor can trigger a check engine light and also register as a failed catalytic converter, random cylinder misfires, camshaft/crankshaft positioning codes, and even transmission codes.Typically a replacement oxygen sensor can save you a lot of headaches and misdiagnosis. Poor fuel economy, stuttering engine, or a foul rotten egg smell? These are a few of the common symptoms of a bad oxygen sensor that if caught early enough can prevent more of the serious damages listed above.

At Lou’s Custom Exhaust of Hyannis, Plymouth, Quincy, and Westport we have the ability to read any check engine light and diagnose the cause to either a faulty sensor, catalytic converter, or any other emissions issue that may be related to the check engine light.

Why Install a Dual Exhaust?

Why Install A Dual Exhaust?


Dual exhausts can be applied to many vehicles that don’t come dual from the factory. They can be run on almost every single pickup truck and many SUV’s. People pick a performance style dual exhaust for 3 reasons.

1) A performance dual exhaust has a great sound to it. If you are a person who is into the sound of performance exhausts you know exactly what we mean. If you are curious head on over to your youtube page and check out some sound clips.

2) A performance dual exhaust, when driven gently, will actually increase your overall fuel mileage.

3) A performance dual exhaust, last but not least, also gives you a horsepower/torque gain from your motor.

Lou’s Custom Exhaust carries only high quality material, from a line of popular stainless performance mufflers, polished stainless tips, and thick, 14 gauge aluminized and stainless steel tubing.

Typically the job requires about two hours to complete. All the pipe is bent in the shop, and fully welded and checked for leaks and also comes with a 2 year warranty. The tips can be picked from a variety along the wall in each shop showroom, and a choice between three different brand mufflers as well.

What do I need to have my car ready for the spring and summer?

What pre-spring maintenance do I need?

Spring is almost here! Though you may be ready for the warm weather, how ready is your vehicle? You should really think about having your brakes and exhaust checked after the winter driving season as it tends to be toughest on our cars. 

1. Give your vehicle a “brake”

Slush and salt take their toll on many components of your vehicle, and disc brake mechanisms are some of the most critical parts affected. Winter driving can cause corrosion issues inside the braking system – if you haven’t had your car’s brakes checked in the last year, now is a great time to do so. We here at Lou's can ensure that the brake caliper sliders are moving freely and are well lubricated. If these stick or seize, they can cause a hard brake pedal and accelerated lining wear. Our brake checks are free!

You should also have the fluid checked. Brake fluid is hydroscopic (absorbs moisture easily) and moisture in the brake system degrades the performance of it significantly.

2. Check that Exhaust System

The snowbanks and deep snow we have seen this winter can damage your exhaust without you knowing it. A slight bump could sperate a hangar, which you wont hear, but will add stress to other parts of the system. We see this all the time and almost every time this increased stress ends up breaking a more expensive part of the exhaust that could have been salvaged at a fraction of the cost if only the hangar was seen and fixed early.

3. Remote Starters

Did you get sick of having to go out into the cold and get into a cold car just to start it and warm it up?   Lou's now installs remote starters for your winter driving convenience!   Swing by before next winter hits if you are thinking about installing one.

4.  Car Lighting

Spring is also a good time to improve your overall driving experience with an LED lighting kit by WEISE.  Lou's now installs these kits, same day!   An LED lighting kit is not only more efficient and long lasting than the halogen bulbs, they also light the roadway better allowing you better visibility at night and during bad weather!

What is a flex pipe?

What is a flex pipe and what does it do?

A flex pipe is flexible piece of pipe that allows the exhaust system some flexibility. Flex pipes are an essential part of any front wheel drive vehicle and on most all wheel drive vehicles. On front wheel cars, since the motor is mounted transversely, when you accelerate the motor rocks and the flex pipe protects your exhaust system from breakage. Without that extra flex the rocking motion would crack the exhaust system causing a loud leak.

It is sometimes very easy to notice a flex pipe that is starting to break down.During the beginning stages you may just hear a slight exhaust leak during your vehicle's start up and it will go away for the most part due to it not having a major leak, but when it finally does let go you will know it! Most flex pipes will break from the inside accordion piece and it will sound as though you have no exhaust whatsoever. Other forms of a flex pipe leaking can be caused by your car bottoming out and tearing the outer protective mesh and scraping a hole into the flex tube or it could just be from deterioration. Here is an example of what a damaged flex pipe and a new one look like:

Occasionally customers will ask do i really need this piece and the answer is YES you do! Not having a flex pipe installed can cause serious damage to your exhaust system such as breaking bolts, flanges, and even the exhaust manifold itself. A typical flex pipe install can take us less than a half hour of your time so we can get you back on the road doing what you need to do!

There are a lot of exhaust shops out there that want you to replace an entire section of exhaust, most of which include a catalytic converter and can be very expensive and time consuming. At Lou’s Custom Exhaust this is not the case! We have the ability to cut out the old flex pipe and weld in the new one for a fraction of the cost of other places or the dealership. At Lou’s Custom Exhaust of Hyannis, Westport, Quincy, and Plymouth if your car is noisy come on down and we will take care of it!

To Flow Or Not To Flow, That Is The Question


Manifolds Or Headers: To Flow, Or Not To Flow, That Is The Question…

In most production engines, the manifold is an assembly designed to collect the exhaust gas from two or more cylinders into one pipe. Manifolds are often made of cast iron in stock production cars, and may have material-saving design features such as to use the least metal, to occupy the least space necessary, or have the lowest production cost. These design restrictions often result in a design that is cost effective but that does not allow the engine to breathe efficiently. Inefficiencies generally occur due to the nature of the combustion engine and its cylinders. Since cylinders fire at different times, exhaust leaves them at different times, and pressure waves from gas emerging from one cylinder might not be completely vacated through the exhaust system when another comes. This creates a back pressure and restriction in the engine's exhaust system that can restrict the engine's true performance possibilities.

A header is a manifold specifically designed for performance. During design engineers create a manifold without weight or cost in mind, but instead for optimal flow of the exhaust. This design results in a header that flows much more efficiently than stock exhaust manifolds. Headers are generally circular steel tubing with bends engineered to make the exhaust flow from each cylinder's exhaust port to the common outlet all equal length, and joined at narrow passage ways to encourage pressure to flow through the outlet and not back towards other cylinders. In a set of tuned headers the pipe lengths are carefully calculated to enhance exhaust flow to be matched within and rpm range.

Headers are generally made by aftermarket automotive companies, but sometimes can be bought from the high-performance parts department at car dealerships. Generally, most car performance enthusiasts buy aftermarket headers made by companies solely focused on producing reliable, cost-effective well-designed headers specifically for their car. Headers can also be custom designed by a custom shop. Due to the advanced materials that some aftermarket headers are made of, this can be expensive. Luckily, an exhaust system can be custom built for any car, and generally is not specific to the car's motor or design except for needing to properly connect solidly to the engine. This is usually accomplished by correct sizing in the design stage, and selecting a proper gasket type and size for the engine.

Most instances replacing stock exhaust manifolds with aftermarket headers is not only better for your engine but better for your wallet as well. Factory replacements can easily equal out to the cost of a nice set of stainless headers. Another thing to consider is the life and longevity of the parts you are putting on, typically if your manifolds on your 07 pickup came off looking like swiss cheese with 56,000 miles on them it will happen again using the same exact parts. If you're planning on keeping the vehicle why not upgrade to a nice set of stainless headers that will in most cases out live the vehicle, Not to mention the increase in horsepower, torque, and fuel economy. Most factory replacements also carry little to no warranty as opposed to say Gibson headers which carry a lifetime limited warranty! Either way you choose to go when it comes to manifold leaks don't waste too much time, the leak can be bad for your engine and the noxious fumes are bad for you!

How is a Quiet Muffler Designed

Ever wonder how a quiet, stock replacement, muffler works?  Look no further, we will explain below!
 
Mufflers are very interesting. They can improve your car’s performance. They can cancel out sound or add sound to the rear of your vehicle. Here’s how they work!

Located inside the muffler is a set of tubes. These tubes are designed to create reflected waves that interfere with each other or cancel each other out. Take a look at the inside of this muffle: 
 

muffler-cutopen.jpg

 
The exhaust gases and the sound waves enter through the center tube. They bounce off the back wall of the muffler and are reflected through a hole into the main body of the muffler. They pass through a set of holes into another chamber, where they turn and go out the last pipe and leave the muffler.

A chamber called a resonator is connected to the first chamber by a hole. The resonator contains a specific volume of air and has a specific length that is calculated to produce a wave that cancels out sound.

As always we do free estimates on exhaust systems, brakes, and other components.  Give a call or come by today, all of our shops are open Monday - Saturday from 8:30am - 5:30pm.

Don't Replace It, Repair It!

Should I Repair or Replace My Exhaust? 
  

Many times an exhaust issue ends up costing hundreds of dollars in parts to repair. Here at Lou’s Custom Exhaust in Hyannis, Plymouth, Quincy, and Westport we custom fabricate our replacement parts saving you a ton of money in the process without sacrificing quality. Great examples of this are catalytic converter issues and front flex pipe section repairs. In most cases it is less expensive in the long run to repair the parts you already own rather than purchasing a new ones.  We are also great at fixing plow truck exhausts which typically have manifold/downpipe issues.

  
For example, the cost on a flex pipe replacement ran range anywhere from $400.00 all the way up to over $1000.00 (if it has converter(s) built in). Here at Lou’s we can repair the flex section instead of replacing the entire pipe for under $175.00, parts and labor, on all but a very few specific systems. Not only that but our flex, unlike any you buy aftermarket, will come with a 2 year parts and labor warranty 
 

Our catalytic converter replacements can save even more. If you have ever had one done you know the cost is very high, usually over $1000.00 installed. At Lou’s most catalytic converter repairs cost you $300.00 installed ($400.00 for california emissions vehicles, the part costs more) saving you tons of money.

Why Use A Performance Exhaust System?

Why Use A Performance Exhaust System?

 
There are several reasons to go with a performance exhaust system.
 
1) A performance exhaust can have a great sound to it. If you are a person who is into the sound of performance exhausts you know exactly what we mean. If you are curious head on over to your youtube page and check out some sound clips.  We also have ways to increase performance with minimal sound increases.
 
2) A performance exhaust, when driven gently, will actually increase your overall fuel mileage. 
 
3) A performance exhaust, last but not least, also gives you a horsepower/torque gain from your motor. 
  

The performance brands we carry are Borla, Flowmaster, and Magnaflow and we stock mufflers to fit almost every vehicle.   


A performance exhaust can be installed on just about any vehicle. At Lou’s Custom Exhaust in Hyannis, Quincy, Westport, and Plymouth.  We will let you choose from a variety of mufflers that are on hand as well as a variety of stainless steel tips. We carry aluminized piping as well as stainless steel. Everything is welded together, double checked for leaks, and come with a full 2 year parts/labor warranty.

How Are Exhaust Tips Made?

Ever want to spruce up the look of your car with an exhaust tip? Ever wonder just how they are made to shine and how to keep them that way? Well look no further all your answers are here! 

How is the metal polished?

 The process of polishing the metal is called buffing. Buffing allows you to smooth a dull metal surface to a bright, shiny, mirror-like finish. The buffing process consists of wearing down the metal with progressively finer grades of grit paper, then polishing it to a high shine with a series of buffing compounds. The process can be completed by hand, but is faster and easier to use power tools, such as a buffer, drill with a mandrel and sanding and polishing disks. 

How are tips chromed?
 
Some Tips are chromed. Chrome or chroming is basically the process of adding a layer of chromium, or chrome plating, to the tip with electricity. Chrome plating a tip includes these stages: 
 
•Degreasing the metal to remove heavy soiling 
•Manual cleaning to remove any left over dirt and surface impurities 
•Pretreatments to help the electroplating process on the steel 
•Placement into the chrome plating vat, where it is allowed to warm to solution temperature 
•Application of electric plating current for the required time to attain the desired thickness of chrome 

Keeping Your Tips Clean 

 Once you get those nice tips you also will want to keep them clean. Cleaning procedures vary depending on your specific exhaust tips but the following procedure will give you an idea of what it takes to clean your chrome or stainless steel exhaust tip. 
 
•Wipe down the inside of the tips using a microfiber towel. This will remove initial carbon deposit and soot. 
•Use a gentle cleaner inside and outside of the tips. This will help break down the carbon deposit and hard water spots on the tips. 
•Use OOOO steel or finer (not an sos pad) to further break down carbon deposit and hard water spots. 
• Dry tips by gently wiping with microfiber towel removing any water spots 

With over 50 tips to choose from your car/truck should never go tipless. Sick of looking at that rusty pipe have Lou’s install a polished stainless steel tip on your ride. It wont affect the sound of your car/truck at all but give it that finished look. Even if you have factory tips on your vehicle now we can easily cut them off and install ones of your choice. All of the tips are welded on. Our tips are $75.00, including welding.

Who are we?

Who is Lou’s Muffler and Brake, of Hyannis, Plymouth, Quincy, and Westport?

  

Lou's Muffler and Brake in Hyannis, Plymouth, Quincy, and Westport are independently owned and operated custom exhaust shops specializing in the fabrication of stock replacement and performance exhaust systems. We pride ourselves on our fabrication and welding skills developed through years of training and experience.  These 4 shops share philosophy and employees.

 Low Price

   First thing you will notice is that we don’t charge you anything to look at and diagnose your car’s issue. At many shops you will be hit with a standard $100, or more, “diagnostic fee”.   Then there is the exceptional value pricing of our work. We keep the price low and quality high because we start with raw materials; straight 14 gauge pipe, mufflers, and hangers. Our highly trained employees fabricate your exhaust system to your vehicle specifications.

The advantage: a perfect fit and cost savings to our customers. National chain shops buy pre-bent exhaust systems from their franchisors at very high prices and pass this cost to their customers.   Lou's of Hyannis, Plymouth, Quincy, and Westport do not have middle men—so our prices are typically hundreds of dollars less.  

1) We fabricate our own exhaust piping and repair parts keeping the cost of the replacement parts much lower

2) There are several shops that buy materials together in bulk further reducing the prices on materials

3) We can cut and weld replacement parts, such as catalytic converters, into stock systems saving the customer hundreds of dollars

4) We cut out the middleman.  

On most typical repairs we can save you, the customer, anywhere from $100 all the way up to thousands of dollars. A perfect example of this is replacing the front flex pipes on an Audi A4. These parts have a catalytic converter built into them. To replace both flex pipes here it would cost you under $400.00 for BOTH sides. The factory part, unistalled, costs $700 per side. Aftermarket you can typically get them for $325.00 per side. By fabricating this ourselves we can save you over a thousand dollars.

Throttle Body Spacers

What is a Throttle Body Spacer and What Does it Do? 

 


Throttle Body Spacers work by swirling the air coming through the intake to maximize the airflow going through it. It is a generally inexpensive inch-thick piece of metal that bolts up directly to your throttle body.

 

 



An aftermarket air intake can help increase the airflow even further, and in turn increase engine horsepower, torque and even fuel economy. Many people will even port their throttle body and/or intake manifold, to maximize airflow even more.

Throttle Body Spacers are just one of many aftermarket performance accessories that Lou’s Muffler and Brake can install onto your vehicle. Call for a free quote today

Need More Power Out of Your Turbo?

Bolt on exhaust modifications are a great way to get more horsepower out of your turbocharged vehicle. Turbo charged cars and trucks benefit from that extra exhaust flow that a turbo back exhaust system provides. Turbo back exhausts accomplish this increased flow by widening the pipe size and removing restrictive factory bends. With this type of modification you will immediately notice an HP gain. The increased flow with wider diameter pipe will also allow the turbo to spool up a lot faster. Finish it off with a custom tune and nice performance muffler and the difference will be like night and day. 
 
We know that most people, when going full turbo back exhaust, will want to do so without the catalytic converters installed. Unfortunately this is illegal in our state of Massachussettes so we can not install parts without the emissions devices (catalytic converters) on them. This is why we provide the high flow converter option, so you can still get that power increase but remain street legal at the same time! The high flow converter will allow your turbo to generate more boost than a factory flowing converter as it will allow more exhaust to be scavanged from the engine. 
 
To get the full benefits out of your turbo back exhaust it is reccomended you have the car custom tuned for the modification after. The increased flow will allow a tuner to drastically increase the level of boost in your turbo which will create a lot more tourque and horespower. 
 
Here is a dyno graph (cobbtuning.com) example of what a turbo back exhaust can do for a car like a Subaru WRX. The stage 1 numbers are a tune only, the stage 2 is the turbo back. 



 
Although these mods can be done in your driveway it is always better to have a professional install the parts then get a proper tune from a local tuner to compensate for the increase in flow. The tune will make these upgraded parts work how they were designed and most important make it safe for the car. With these simple upgrades your turbocharged vehicle will appreciate the HP gain.

You know us for Muffler Repairs but we also do Brakes, Suspension, Tune Ups and more!

At Lou’s Muffler and Brake of Hyannis, Plymouth, Quincy, and Westport we do more than just exhaust work.  We also do brake work, tune-ups, struts, and other under car repairs. We give free work estimates, including brake inspections.  If our technicians find your car needs attention we can usually fix it the same day.

Here is some information about our brake services: 

 
Brake Fluid Flushes 
 

 
Believe it or not your brake fluid is not suppose to look like molasses! Brake fluid, like brake hardware, isn’t indestructible. Parts such as the rubber in the valves in the master cylinder, calipers and wheel cylinders deteriorate. All the little bits that flake off end up in your brake fluid. Plus the fluid itself can get old and worn out. Moisture can also get in the system which leads to rust, which leads to more particles in your brake fluid. All this adds up to a brake system with compromised stopping power. Think of it this way, you wouldn't skip changing your car's engine oil, right? It's the blood of your engine, and when it gets contaminated by impurities, you put the entire engine at risk. It's the same with brake fluid. Let it get dirty and you won't be able to stop as well. It may not seem like a big deal when you're standing at the service desk and the mechanic asks if you want him to flush your brakes, but when you're careening down that mountain road, you'll understand why it's an important part of vehicle maintenance. 
 

If you're a do it yourself type of person (which we know many people are now a days) to check your brake fluid is only a hood pop away! Color and consistency are the two major signs of deteriorating (read bad) fluid. Visually fluid should be a light golden yellow color, the darker it gets the dirtier and contaminated it has become. Also meaning the viscosity is wearing out AKA you're losing the lifeline of your brakes! Typically if you start when your vehicle is new a good interval for a brake fluid flush is every 25k-35k miles. The longer you go without flushing the fluid the more corrosion build up meaning more problems can arise. In the big picture of the things spending money now could save you thousands in the future. Not only in damage to your vehicles braking system but without brakes your vehicle becomes a weapon, putting others at risk! 

 
Brake Inspections. Pad, Rotor, Caliper, and Line Replacements 
 


 
The only thing better than a car that goes is a car that stops. Routine inspections keep your vehicle stopping safer, longer. How often you have to change your brakes depends on a lot of things driving conditions, rotor thickness, quality of brake pads, and more. A routine brake inspection makes certain that your braking system is safe. 
 

Lou’s Muffler and Brake is proud to offer free brake inspections at the Hyannis, Plymouth, Quincy, and Westport locations. Our professional technicians will visually assess your brakes to determine if any service or repairs are needed. 

 
A few signs your brakes might need service or replacement: 
 
 •Brake pedal is low or spongy (goes to the floor when pressed) 
 •Brake pedal is hard to depress (won’t go down at all) 
 •Brake service warning light stays lit at all times 
 •Squealing or grinding at stop 
 
So if you are experiencing any of these symptoms please swing by one of our shops for a free estimate

What is a “Tune Up” all about?

After "oil change," the phrase, "my car needs a tune-up" is the next most popular request heard in the automotive service and repair industry. When a service writer or technician asks the driver why the vehicle needs a tune-up, the customer usually says that the vehicle is not "running right."

Maybe it's idling rough. Maybe it's hard to start. It could lack power, get poor mileage, or have many other symptoms. Many people believe that a tune-up will solve all or most of these problems, but the truth is, modern cars do not require tune-ups and poor performance almost always means the car needs a repair.

The phrase "tune-up" is from a time when automobiles were not computer controlled and an auto mechanic could actually adjust the timing, idle speed, fuel mixture, and other things in order to "tune up" the operation of the engine, similar to the way a piano tuner will tune up a piano to bring it back into proper pitch and operation by adjusting the tension on the strings, adjusting the action, and reshaping the hammers.

Maintenance: The Modern Day Tune-Up

Nowadays, the term "tune-up" actually refers to replacing and servicing the wear items in the ignition and fuel system. For example:

  • The air filter and fuel filter will become less efficient and need replacing
  • The spark plug electrodes will wear down and need replacing
  • Because of oil vapors produced by the positive crankcase ventilation (PCV) system, the throttle body and fuel system will need to be cleaned and/or de-carbonized

The vast majority of the time, there are no adjustments needed (or possible), because the engine computer controls all the functions of the ignition and fuel system. The "tune-up" is often part of a large 30,000/60,000/90,000 mile service that includes inspections, and fluid and filter changes. These services are part of the manufacturer's recommended scheduled maintenance detailed in the owner's manual.

The modern vehicle should not exhibit any performance problems by the time a tune-up is due. If there are any performance problems, usually a Check Engine Light will illuminate, indicating that the vehicle needs some attention because it is not running properly and is polluting the air.

Tune-Ups: Some Historical Perspective

Up until the mid 1970s, most gasoline-powered cars and light trucks had spark plugs, spark plug wires, a single ignition coil, a distributor cap and rotor, a set of ignition points, and a condenser. A carburetor would combine the fuel with air and then deliver this "mixture" to the cylinders. All of these components needed regular adjustments, or "tune-ups."

Compared to the vehicles of the 21st century, these technologies were very crude and required a lot of care and multiple tune-ups to properly maintain them. The spark timing would go out after 10,000 miles of driving because the ignition points would wear and become pitted or burnt. The spark plugs would foul and not work properly because the carburetor would get dirty and varnished from all of the oil vapors being recycled into the air cleaner from the positive crankcase ventilation (PCV) system. This varnish would plug up the air bleeds in the carburetor and prevent it from mixing the fuel properly with the air. The spark plug wires were usually damaged from oil leaking on them from the older style cork-and-rubber valve cover gaskets. It was common for a vehicle to need a "tune-up" every year, or even more often if the vehicle was driven more than 10,000 miles per year.

By the mid 1980s, most vehicles had one or two computers involved with the management of the engine operation because the Environmental Protection Agency found that when cars needed tune-ups, the amount of tail pipe emissions they were producing was increasing exponentially.

The ignition system was the first to receive electronic and, later, computer controls. The ignition points and condenser were replaced by a transistor controlled ignition module that could last the life of the vehicle. Once the ignition timing was set, it could stay properly adjusted for 30,000 miles or more. Valve covers and valve cover gaskets started using air craft engine designs and would not leak for over 90,000 miles. This meant that the spark plug wires could last upwards of 60,000 miles before they failed electrically.

By the mid 1980s, electronic port fuel injection was phasing out the carburetor. The ratio of the air fuel mixture was now computer controlled. This allowed for precise compensation to reflect the ever-changing demands put on an engine due to ever-changing driving and weather conditions. Fuel injection is not nearly as vulnerable to the PCV oil vapors because there are individual injectors for each cylinder located away from the flow of the vapors.

By the late 1990s, most vehicles were using individual coils for each cylinder and the spark plugs had platinum-tipped electrodes, which eliminated distributor caps and rotors and most ignition wires. Platinum-tipped spark plugs could easily go for 60,000 miles, as opposed to the usual 30,000. Some manufacturers were advertising cars that could go 100,000 miles without a "tune-up" until it was discovered that spark plugs rusted into the cylinder heads. A major repair, costing hundreds if not thousands of dollars, was required to remove them. This is why 60,000 miles has proven to be a much more realistic and reliable mileage interval and why many manufacturers are switching back to this recommendation.

Home For Spring Break? Get That Car Looked At!!

Check That Car Over Spring Break!!!

Everyone is home from college for spring break! Its time to start thinking about if your car, or your student's car, is ready for the rest of the school year before they go back! But how do you know if your car is ready? Easy, bring it to us at Lou’s for a free inspection and readiness check! 
 
What is involved? 
 
With every vehicle there are numerous things to keep in mind when inspecting, such as your exhaust, brakes, battery, tires, cooling system, and oil. With that in mind, here's some advice on what to think about when you're getting your car ready for another season of cold. 
 
Brakes 
 
A VERY important item for any season and any car. If your brakes are wearing out parts of your ABS (anti-lock braking) system may not be working properly. This can cause dangerous conditions in the snow. We do free brake estimates at Lou's so we are the best place to come to find out if you need work or not. Our repair prices are highly competetive on braking systems 
 
Exhaust 
 
I know some of you are reading this and saying "What does my exhaust have to do with being safe going back to school?" Normally the exhaust isn't an issue.  However, if for some reason you get stranded out in the cold and the snow with only your car to keep you warm an exhaust leak will all of a sudden become very noticeable. You don't want to be in a bad situation and not be able to run your car for heat due to an exhaust leak so come on in to any Lou's location for a free exhaust inspection. 
 
Tires 
 
As the only part of your car that actually touches the road, making sure that your tires are good is probably the first and most important thing to take into account when inspecting your vehicle. While making sure that your tires are rotated and aligned is important, checking the tread on your tires is probably the first thing that should be checked on your new and used cars. 
 
If getting your car to your local Lou's isn't a viable option, then an easy way to check the tread on your tires is to take a penny and insert it into the most worn section of your tired tread. If you are able to see Mr. Lincoln's head, then it's time to get your tires replaced, preferably before there's snow on the ground. Depending on the region you live in, then checking the tread on your tires might not be enough, and you may need snow tires to make it through the winter. Figure out which option will best suit your needs and make sure that you have everything taken care of before the first flakes of snow fall. 
 
At Lou's we can check your tread, check your tire pressures, rotate your tires, and check your braking system too. We have local shops whom install tires if we find you should do so! 
 
Cooling System 
 
We know that with winter on its way it seems counter-productive to be thinking of your cooling system, but your cooling system is also what houses your anti-freeze, which is very important to making it through this winter. While you should change out the anti-freeze in your car every two years, it's always a good idea to have it checked before the start of every winter. Swinging by any Lou's Custom Exhaust location is a quick way to have your anti-freeze levels checked and make sure that you won't have to worry about your car freezing up. 
 
Things to check are fluid level, condition, and mixutre of water/coolant. Too much water in the water/coolant ratio could cause freezing and internal engine damage! 
 
With having your anti-freeze checked, it's not a bad idea to pour one of many anti-freezing chemicals that are designed for your fuel lines. This can help to prevent any moisture that's in your fuel line from freezing up and preventing your car from starting or damaging the fuel lines which can add up to costly repairs. 
 
Battery 
 
Make sure that your battery's terminals are clean and tight, ensuring a good connection for your electrical systems. Getting the charge checked on your battery before going off to school is a good way to make sure that you won't have to have your care jumped at the worst time. 
 
We can clean your terminals at Lou's and get replacement batteries for you if your battery has been getting weak. 
 
Heater and Defroster 
 
Make sure that your heater and defroster work before heading off to school for the winters. Not only is this important for your own comfort inside of the car, but it's important for ensuring that you'll have good visibility through your windows. 
 
Emergency Kit 
 
If you don't already have an emergency kit in your car, now is a good time to make one or buy one. A warm blanket, jumper cables, an ice scraper, de-icer, rock salt or sand, a tire inflator, a flashlight, and a few snacks are essential parts to any snow emergency kit. If you already have one, check to make sure that everything in there is still in good shape and easily accessible. If for some reason you do have car troubles and are stranded you'll want these things to help make it until help arrives.


Getting your car ready for the school season doesn't have to take long, but not getting it done can cost you a lot of money and stress when you have to get these things repaired in the middle of the winter season. Save yourself some time, money, and protect your safety by coming to one of our locations to get your car checked out and ready for the winter season as soon as possible!
