But thereís more to the exhaust system
than just the muffler.
The exhaust system has three main functions:
Exhaust gas is poisonous. You donít want
it getting into the passenger compartment. For example, carbon

exhaust system, exhaust could get into the
passenger cabin and make you sick or even kill you.
If you smell exhaust in the vehicle,

You may smell or see exhaust coming from the engine compartment
or under the vehicle if you have a leak. Sometimes the sound
from an exhaust leak is loud and obvious. Sometimes itís a
ticking sound when you start the engine that goes away as you
drive. That could be a small crack or a

environmental issues for our Providence and Warwick RI communities.
Exhaust gas contains a number of pollutants and
particulates. The catalytic converter scrubs some of
those harmful substances. And diesel vehicles have systems to
deal with soot.
