Flowmaster History


41 years ago, Flowmaster® mufflers were conceived to solve 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 and many patents protecting the various technologies used in Flowmaster® products. With those developments, Flowmaster ushered in a revolution in automotive performance exhaust.
