People sometimes think automobile exhaust systems and mufflers are the same thing. In fact, your exhaust system is much more than that. It is a series of pipes that run under your car connecting the muffler and catalytic converter.
Exhaust systems play an important role not only in keeping your vehicle running well and quietly, they also protect your health and well-being. Exhaust systems convert waste, created by fuel burning, into less harmful byproducts and direct them, and carbon monoxide, to the rear of the vehicle, safely away from passengers. They also serve to direct exhaust gases to heat air and fuel before the fuel goes into the engine's cylinders. Finally, the exhaust system provides the correct amount of back pressure into the engine to improve its fuel-burning efficiency and increase performance.
