A car exhaust system has three essential functions. They include:
To direct all exhaust fumes from the engine to behind the vehicle
To reduce emissions by decreasing the number of toxic chemicals in the fumes
To reduce the noise caused by the explosions which occur during the fuel combustion process.
A car exhaust system consists of many chambers and pipes. It begins at the engine and goes all the way to the tailpipe at the back of the vehicle.
Most vehicles have four-cylinder engines with a single exhaust. High performance and ‘sporty’ cars like a V8 generally will have twin exhausts.
