Flowmaster History 37 years ago, Flowmaster® mufflers were conceived as a solution to a growing problem with sound issues at race tracks in California and beyond.

Now you can pick up an entire performance package in one place and from a company with a name you know you can trust, Flowmaster. Like today’s cars, trucks, SUV’s, Jeeps and UTV’s we too have evolved.
