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
