About Your Exhaust System and Muffler

Many people believe that the exhaust and muffler are in place to simply dampen automotive noise. While this is true, the system is also created to reduce the level of noxious gases emitted into the air. The system consists of a number of parts that may fail at some point and require replacing.

The system begins behind the engine where manifolds attached to the cylinders capture exhaust gases coming from the engine. The gases then travel through the system where sensors analyze oxygen levels. The catalytic converter removes harmful components of the gases before they are released via the muffler and exhaust pipe.

If you notice an increasing noise level when accelerating, you may need your exhaust system evaluated for problems. A faulty system or possible blockage somewhere along the line might also hamper your gas mileage.
