BMW 323i Exhaust Parts

2013 BMW 750i

Change vehicle

The factory exhaust system on your BMW 323i car is responsible for safely handling and dispersing any noxious fumes generated by your engine's combustion process. Some components also help to reduce the amount of noise produced by the process.

There are several stages to the exhaust process. First, pollutants pass through the catalytic converter. The cat contains metals like platinum, rhodium, and palladium, which capture the toxic molecules and separate them into nitrogen and oxygen. The oxygen continues on, while nitrogen remains trapped. This process consumes both hydrocarbons and carbon dioxide, leaving little more than water vapors and carbon dioxide.

The gases continue through the exhaust system to the exhaust pipe, while the resonator and muffler work together to dampen the noise and maximize airflow. Finally, the harmless gases exit the tailpipe and release into the atmosphere.

How to Recognize Exhaust Issues

Eventually, even the highest-quality exhaust system parts can go bad. When that happens, you're polluting both the air that you breathe and the atmosphere in general. Signs of trouble include:

  • Worsening fuel economy
  • Strange noises coming from your exhaust pipe or muffler
  • The distinctive odor of rotten eggs
  • The "Check Engine" dash warning light comes on
