 » DID YOU KNOW?
Most exhaust systems are also referred to as cat-back exhausts. This is because in general, aftermarket exhausts are made to start from the catalytic converter and go back. So in general M exhausts include all the exhaust piping starting from the catalytic converter and going back, including the muffler and muffler tip(s).

Some manufacturers make axle-back exhausts, which do not include the segment of exhaust piping between the catalytic converter and the rear axle of the vehicle. Our product descriptions will denote if any M exhaust system is an axle-back.

Many people buy exhaust systems so their car or truck will sound better. Lucky for us, many manufacturers do sound testing as part of the R&D process when engineering their exhaust systems. So there are a lot of good products on the market to choose from. If manufacturers make sound clips available for exhausts, we will have a link to it from the detail page of the product listing for the part. Otherwise, as a general rule of thumb, you get what you pay for when it comes to M exhaust systems, meaning that the more affordable ones are an upgrade over your factory exhaust but probably won't sound as good or perform as well as the ones that cost more. The higher cost is normally attributed to large R&D expenditures in most cases, meaning you should expect better sound and air flow from the ones that cost more.
