A muffler is an important component of an engine's exhaust system. The muffler is found near the back of a vehicle, and its purpose is to reduce the noise produced from the exhaust process.
Once the new muffler is in position, the car is started and the mechanic will make a detailed check for gas leaks and vibration. A check is also made to ensure that the muffler is not fouling on the underside of the car. The car can then be taken on a short drive to check for any noise or vibration.
