Your car’s exhaust system does more than just muffle engine noise. It also removes harmful gases from the engine, helping to keep both you and the environment safe. The system is made up of four parts: the exhaust manifold, catalytic converter, muffler, and tailpipe. Here’s a closer look at each one.
Exhaust Manifold
The exhaust manifold is connected to the engine at the cylinder head. Its job is to collect the exhaust gases from each cylinder and funnel them into the catalytic converter.
Catalytic Converter
The catalytic converter contains a chemical catalyst that helps to convert harmful gases-such as carbon monoxide-into harmless ones. This process happens as the gases travel through a honeycomb-shaped structure that’s coated with platinum and palladium.
Muffler
The muffler is located between the catalytic converter and the tailpipe. Its job is to muffle engine noise as the exhaust gases travel through it. The design of a muffler can vary depending on the make and model of your car. However, most use either a perforated pipe or some type of sound-absorbing material-such as fiberglass-to deaden noise.
Tailpipe
The tailpipe is located at the back of your car, past the muffler. Its job is to expel the now-quieted exhaust fumes from under the vehicle. Most tailpipes have a flared end that helps to dissipate any remaining noise.
Your car’s exhaust system plays an important role in maintaining both your safety and that of the environment. Consisting of four parts-the exhaust manifold, catalytic converter, muffler, and tailpipe-the system works to remove harmful gases from your vehicle’s engine. To keep your system functioning properly, be sure to have it regularly inspected by a qualified mechanic.
