The exhaust system and muffler are essential automotive components that keep emissions low and keep vehicle cabin air breathable. Most mufflers last an average of five to seven years, according to our Bald Hill Dodge Chrysler Jeep Ram service department techs. Here's how exhausts and mufflers relate to each other.

A muffler is part of a vehicle's exhaust system. The exhaust system captures harmful gases, neutralizes them and expels them via the tailpipe. It begins in the exhaust manifold, which collects noxious, poisonous fumes from the engine's combustion chamber cylinders. Later, catalytic converters change the gases into water vapor and carbon dioxide to be released into the atmosphere through the tailpipe.
How Mufflers Work
Before water vapor and carbon dioxide enter the tailpipe, the exhaust gases and sound waves from the engine enter the muffler. The muffler consists of a series of tubes or holes. As sound waves move through the muffler, the muffler alters the acoustics and intensity, muffling the engine sound waves for a quieter, less rumbling commute on highways in Warwick.
