Exhaust system is an integrated set of equipment that carry the gas created
as a result of internal combustion to the rear of the vehicle.
The system contains components which perform the functions
of noise attenuation, conversion and cooling.
This is why it is called exhaust ''system'' instead of a simple exhaust pipe.
Composition of an exhaust system are different depending on the vehicle types, number of cylinders and how they are placed. This illustration shows names of each component of an exhaust system and its function, using as an example of V-6, vertical, front-engine.
