BMW 128i Mufflers

Your BMW 128i has a muffler for a very good reason. It's designed to reduce the noise created as your internal combustion engine burns the mixture of air and fuel that powers you down the road. As such, it's essentially a noise deadening device that’s part of your overall exhaust system.

What Mufflers Do

Your exhaust is responsible for handling the toxic gases created by the combustion process. Some are broken down into less harmful compounds by the catalytic converter before the gases are routed through piping and into the muffler.

The muffler features a silencer that suppresses the engine noise, and reducing any high-pitched frequencies. Together with the resonator, your muffler also ensures that airflow isn't restricted, since that can create a back pressure that lowers the engine's efficiency. As a last step, the muffler directs the gases to the tail pipe, which releases them into the atmosphere.

Even the best muffler can fail. When that happens, your engine performance may suffer. You may also draw unwanted attention due to the loud noises coming from your coupe. Replacing a faulty muffler is the best solution.
