Your car's exhaust system is like a superhero that helps keep you safe and your car running smoothly. It's responsible for getting rid of harmful fumes from the engine and making sure they don't sneak into the inside of your car. The exhaust system is made up of several components, including the exhaust manifold, catalytic converter, muffler, and tailpipe. As the engine burns fuel to power your car, it produces harmful gases like carbon monoxide, hydrocarbons, and nitrogen oxides. These gases are channeled through the exhaust manifold and into the catalytic converter, where they are converted into less harmful emissions through a series of chemical reactions. The muffler then helps to reduce noise levels by dampening the sound of the engine. Finally, the tailpipe releases the now cleaner emissions out of the back of your car. Overall, the exhaust system plays a crucial role in maintaining both the performance of your car and the quality of the air we breathe. ... read more

Rust Formation - Moisture residue left behind can lead to rust forming within the brakes. Contamination - Debris, rubber, and metal particles can contaminate th ... read more
