Exhausts vs. Mufflers: What's the Difference

Did you know that a compromised muffler can affect a vehicle's exhaust and result in a check engine light? Why? We put these common customer questions to our HERITAGE MITSUBISHI-MORROW service team. Here's what they said.
The Muffler is Part of the Exhaust System
The muffler is an end part in the vehicle exhaust system. Aptly named, the muffler muffles sound. It does this by transforming engine vibrations and their resonance. The muffler also expedites exhaust system airflow through a series of chambers or pipes containing special holes. This makes a vehicle more efficient.
