OEM BMW Exhaust Parts

The factory exhaust system in your BMW car or SUV collects and removes fumes from the engine cylinders and combustion chamber. It cleans and releases the fumes as a gas, away from your vehicle. That minimizes harmful emissions and helps protect the environment. Your exhaust also muffles the noise produced in the process. Exhaust systems are made up of many parts, but five are most important. One is the catalytic converter, or cat. It uses a special reactive chemical to convert harmful substances into water vapor and carbon dioxide. Another is the exhaust manifold. It's a cast iron or steel piece in a high-efficiency shape. Its job is collecting exhaust gas from each engine cylinder and sending it through the exhaust pipe. Others are your muffler and resonator. Your muffler reduces engine noise while optimizing exhaust gas flow. The better the flow rate, the better your car or SUV works. Your resonator changes the sound of engine vibrations and, along with your muffler, can not only improve performance but also fuel efficiency. Finally, your muffler's tail pipe directs exhaust fumes out of your vehicle and into the air. It can also be a style point. When to replace a catalytic converter depends on quality and driving conditions, but they typically last about 100,000 miles. When to change mufflers and resonators is another question. These last about 2 to 4 years. Signs and symptoms of exhaust problems can include your Check Engine light turning on, reduced fuel economy, abnormal exhaust pipe or muffler noises, and a rotten egg smell indicative of dangerous fumes.
