Genuine Mercedes-Benz Exhaust Parts

FAQs About Exhaust Systems

What Does One Do?

It helps remove the toxic byproducts created as your engine burns fuel and air for power. If your car or SUV didn't have an exhaust, its fumes would make you and your passengers sick, not to mention pollute the environment and likely violate emissions standards and laws.

How Does One Work?

In theory, like an air filter, an oil filter, or fuel filter: it traps pollutants. They pass through the system's catalytic converter first. There, metals such as platinum, rhodium, and palladium contain them, splitting their molecules into nitrogen and oxygen. The O2 flows onward, while the N2 remains behind. Carbon monoxide and hydrocarbons burn up in the process.

Meanwhile, a muffler and resonator cut down on the noise the process makes. They also help make sure air flows properly. An exhaust manifold then shunts the resulting cleaner gases (carbon dioxide and water vapor, mostly) down an exhaust pipe. They enter the muffler's tail pipe, flow out into the air, and scatter.

What are the Signs of a Bad One?

Look for warning lights such as Check Engine on the dashboard, along with worsening gas mileage. Smell for what seems like rotten eggs and listen for unusual noises coming from the muffler and/or exhaust pipe.

How Do You Tell What Parts Need Changing and When?

Do an inspection, review its results, and swap out anything recommended. Otherwise, replace the muffler and/or resonator every 2 to 4 years. Replace the catalytic converter, on the other hand, every 100,000 miles.
