Your factory exhaust system is responsible for capturing the toxic byproducts that are created as the engine burns fuel. That helps to keep our air both clean and breathable. The exhaust system also helps to stifle any noise generated by the engine as it consumes that fuel.

What Exhaust Systems Do

First, the fumes pass through the vehicle's catalytic converter. That device contains metals such as platinum, palladium, and rhodium, which capture the toxic molecules and separate them into oxygen and nitrogen. Oxygen continues through the system, with nitrogen held back. This process consumes carbon monoxide and hydrocarbons, leaving behind what amounts to nothing more than carbon dioxide and water vapor.

As the exhaust manifold passes the cleaner gases on to the exhaust pipe, the resonator and muffler team up to minimize engine noise and optimize airflow. Once the gases make it to the exhaust pipe, they disperse harmlessly into the atmosphere.

How to Spot Exhaust System Issues

Eventually, exhaust system parts can go bad. Signs of trouble include:

Worsening fuel efficiency

Odd noises coming from the tailpipe

You detect the distinctive odor of rotten eggs in the air

Your "Check Engine" dash light comes on -- though this needs to be investigated in more detail, as it's a default alert that something's gone wrong
