What parts make up an auto exhaust system?

Auto exhaust systems have come a long way since the invention of the automobile. Early exhaust systems moved exhaust from the engine to the back of the vehicle; today the exhaust system has more duties than the mere movement of fumes. With the increased performance demands placed on the exhaust system, more parts were added.

There are five parts to the modern exhaust system. The exhaust manifold starts the process of exhaust ventilation by collecting the gases emitted by each combustion cylinder. Inside the exhaust manifold sits the oxygen sensor that sends information to the car’s computer to regulate the amount of fuel delivered to each cylinder. Exhaust pipes serve as fume conveyors between parts. The catalytic converter eliminates harmful elements in the fumes. The muffler deadens the sound from repeated explosions inside combustion chambers.
