What is a muffler?

The muffler is the last step for exhaust gas on the way out of the exhaust system. Mufflers reduce the noise created by exhaust gases emitted from the engine to make sure the vehicle drives quietly.

How does the muffler work?

The muffler uses several sound deadening chambers that absorb vibrations as the exhaust gas passes through this forced maze. After passing through multiple chambers and baffles, the exhaust noise is quieted down to the designed level.
