Designed specifically for each model, these pipes are used to properly route exhaust to the back of the vehicle.
Acting like a funnel, the exhaust manifold collects the gases from all cylinders and releases them through a single
opening. Some engines have two exhaust manifolds.
The job of the catalytic converter is to convert harmful pollutants into less harmful emissions before they ever leave
the car's exhaust system.
The muffler is a metal container with holes, baffles, and chambers that reduces exhaust noise.
The resonator works with the muffler to reduce noise.
Found at the back of the car, the tail pipe carries exhaust gases away from the vehicle.
Exhaust System is more
than just a Muffler
Weíve all heard a car or truck in
our urban and even suburban neighborhoods that
needs a new muffler. But thereís more to the
exhaust system than just the muffler.
The exhaust system has three main functions:
Exhaust gas is poisonous. You donít want it getting into the passenger compartment. For example, carbon monoxide
can be deadly. Thatís why you should never run your engine in a closed garage. If you have a
leak in the exhaust system, exhaust could get into the passenger cabin
and make you sick or even kill you.
If you smell exhaust in the
roll down your windows and get it inspected. You may smell or see
exhaust coming from the engine compartment or under the vehicle if you have a leak. Sometimes the sound from an
exhaust leak is loud and obvious. Sometimes itís a ticking sound when you start the engine that goes away as you
drive. That could be a small crack or a
bad fitting that leaks when itís cold but seals up when the metal heats
Now, letís address the
environmental issues for our Northern Illinois communities. Exhaust gas
contains a number of pollutants and particulates. The catalytic converter scrubs some of those harmful
substances. And diesel vehicles have systems to deal with soot.
Catalytic converters eventually wear out and need to be replaced. Theyíre expensive so you want to help
them last as long as possible by keeping the fuel system clean and replacing your
air filter. These components need to be tested for function with an
emissions test from time to time.
And that leaves the muffler. The beauty of getting a new muffler is that you can suit your taste: Some want
whisper quiet and others like a little rumble. And some like a roar when they drive down Rt-59.
