BMW 128i Exhaust Parts

The exhaust system in your BMW 128i is designed to safely and efficiently capture the noxious byproducts generated by the engine as it burns fuel. That keep the air that you and your passengers breathe cleaner, while also benefiting our environment. The system also helps to stifle the noise that's produced during the entire process.

Your exhaust system works in stages. First, the pollutants passing through a catalytic converter where the toxic molecules are captured and separated into nitrogen and oxygen. The nitrogen remains trapped, while oxygen is allowed to continue. This process burns up both carbon monoxide and hydrocarbons, leaving what amounts to water vapor and carbon dioxide.

Next, the exhaust manifold collects the gases and sends them on to the exhaust pipe. At the same time, the resonator and muffler reduce engine noise and ensure optimal air flow. Finally, the tail pipe releases the cleaner vapors into the air.

How to Spot Exhaust System Issues

Eventually your exhaust may start to fail. Fortunately, the signs of that are easy to recognize. They include:

• Worsening fuel economy
• Strange noises from the exhaust pipe or muffler
• The odor of rotten eggs
• The "Check Engine" dahs light comes on
