Understanding the different types of internal configuration will help you pick the right muffler for your application. In this article we are tackling the age old question of how much of high performance muffler design is based on science and how much is slick advertising? With all the different styles and types of performance mufflers on the market with different sound attenuation strategies, it can get confusing to know what is best for your application. Starting from the top we should define what the purpose of a performance muffler is.

It's common to have an exhaust pipe rust through and start dragging on the road after hitting a hole in the road or a bump. More to a safe area and inspect the exhaust system. It's never a good idea to drive a vehicle with a broken exhaust pipe, fumes can enter the passenger compartment and carbon monoxide poisoning can result. Wire can be used to tie up an exhaust system temporarily in the case of a broken exhaust hanger. Catalytic Converters and sometimes mufflers will have a heat shield attached to the top between the exhaust system and the car floor.
Sometimes the car seems to run fine, but an exhaust repair is needed because of internal problems in the engine or throughout the exhaust system.

A muffler silencer in British English is a device for reducing the noise emitted by the exhaust of an internal combustion engine. This noise deadening device is especially one forming part of the exhaust system of an automotive vehicle. Mufflers are installed within the exhaust system of most internal combustion engines. The muffler is engineered as an acoustic device to reduce the loudness of the sound pressure created by the engine by acoustic quieting.
