BMW 320i Exhaust Parts

Filter

Your BMW 320i came with a factory-installed exhaust system, and for good reason. It's responsible for removing the noxious byproducts produced as your engine combusts a mixture of fuel and oxygen. That results in cleaner gases being released harmlessly into the air. A side benefit? Your exhaust system also helps to suppress the noise produced during the combustion process.

How Your Exhaust System Works

It starts with the pollutants passing through the catalytic converter. There, metals such as platinum, palladium, and rhodium capture the toxic molecules and separate them into nitrogen and oxygen. Oxygen is allowed to pass through the system, while the nitrogen remains trapped. This process consumes both hydrocarbons and carbon monoxide, leaving behind little more than water vapor and carbon dioxide.

Then the exhaust manifold collects the cleaned gases and directs them to your exhaust pipe. At the same time, the resonator and muffler team up to limit engine noise and deliver optimal airflow. Finally, those cleaner fumes are released through the tail pipe into the atmosphere.

How to Spot Exhaust System Issues

Eventually, though, even the highest-quality exhaust system components can begin to go bad. Signs of failure include:

  • Worsening fuel efficiency
  • You notice the smell of rotten eggs in the air
  • You hear odd noises coming from the muffler or exhaust pipe
  • Your "Check Engine" dash light comes on
