Exhaust

You are here:

The muffler is the exhaust system component principally responsible for reducing the sounds made by the engine. Mufflers and other exhaust system components are often replaced together because of the worn condition of all the components or because sections are welded together.

The exhaust manifold is responsible for routing the exhaust gases out of the engine cylinder to the exhaust system. Several exhaust pipes also route the exhaust away from the engine, into the catalytic converter, the muffler, and then out through the tail pipe. Exhaust pipes and other exhaust system components are often replaced together because of the worn condition of all the components or because sections are welded together.

The purpose of the exhaust system is to reduce the sounds made by the engine, reduce the temperature of the exhaust, and to control the emissions from the vehicle. The catalytic converter takes the gases created by the combustion of the fuel and turns the gases into more harmless emissions that do much less damage to the environment. Today’s cars often have more than one catalytic converter.
