What does the muffler do? It muffles noise!
The first function of the muffler is muffling noise, or reducing the volume of the engine noise. That’s how this part got its name.
Whenever the exhaust valve opens, burnt gases are released. These gases create super powerful sound waves. To protect your ears—and the ears of other drivers—from these loud sounds, the muffler uses a series of metal tubes to deflect the sound waves from the engine.
The second function is to direct exhaust fumes away from the vehicle. Carbon monoxide and other output can be dangerous to breathe, so the muffler sends them away from the car.
