In 1983, Flowmaster® mufflers were conceived as a solution to a growing problem with sound issues at race tracks in California and beyond. In his successful effort to quiet race cars without reducing performance, our founder refused to accept the status quo of the day and instead pushed exhaust technology beyond common thinking. This led to many firsts in automotive exhaust science.

Depending on your choice of sound, we have patented and proven chambered muffler series that deliver mild, moderate, aggressive, and very aggressive sounds. And unlike other muffler manufactures, we offer numerous muffler models which can control the drone, also known as interior resonance inside the vehicle cab area. Check out all the different series mufflers we offer and find the ones that are right for your vehicles.

Absorption and Glass Pack style mufflers are available in several brands with dozens of inlet/outlet size combinations
