BMW 135i Exhaust Parts

The exhaust system in your BMW 135i is responsible for the safe handling of any noxious gases produced by your engine and its combustion process. That helps to protect our environment and also keeps you and your passengers safe from the dangers of inhaling carbon monoxide. In addition, the exhaust system cuts down on the amount of noise generated by the process.

How Your Exhaust System Works

There are several steps to the process. First, the gases enter the catalytic converter, where toxic molecules are separated into nitrogen and oxygen. The oxygen continues through the exhaust system, while nitrogen remains trapped. Carbon monoxide and hydrocarbons are consumed as this takes place, leaving little more than carbon dioxide and water vapor.

Next, the gases are collected by the exhaust manifold and sent on to your tail pipe. While this is going on, your resonator and muffler are teaming to deliver optimal air flow and cut down on engine noise. Lastly, the exhaust pipe emits the cleaned gases harmlessly into the atmosphere.

How to Spot Exhaust System Problems

If your exhaust system rusts or fails in any way, you're putting both yourself and your engine's performance at risk. Signs of trouble include:

  • You detect the telltale odor of rotten eggs
  • Loss of fuel efficiency
  • The "check Engine" dash light comes on
  • Increased exhaust emissions
  • Weird sounds coming from the tail pipe
