Dear Lou's, I picked up my KIA Spectra last night and just wanted to write in to say that was the easiest thing I have ever done with my car. I also wanted to say that the first estimate I got from another muffler place was 300.00!! My final bill with you was 100.00!! Thank You for saving me 200.00 dollars!! That is quite a huge difference, crazy really. My car is quiet now and I am spreading the good word on how inexpensive and easy it was to have work done on my car at Lou's! Thank You for being so accommodating as well as affordable. Have a great day. ~Tracy July 2010
