A vehicle’s exhaust system is designed to direct harmful gases away from the driver and passengers, reduce the emissions the vehicle releases into the environment, control the delivery of hot exhaust, provide information to the vehicle’s computer to improve vehicle performance, and significantly reduce the amount of noise the vehicle makes.
The only component of the exhaust system that can easily be seen is the tailpipe, located under the back of the vehicle. The entire system, however, is actually much larger and more complex. The exhaust system begins at the engine combustion chambers and runs along the undercarriage of the vehicle, eventually ending with the visible tailpipe.
The major components of the exhaust system include the exhaust manifold, oxygen sensors, catalytic converter, resonator, exhaust pipes, muffler, and tailpipe.
