Collection: Flowmaster
39 years ago, Flowmaster mufflers were conceived as a solution to a growing problem with sound issues at race tracks in California & beyond. In his successful effort to quiet race cars without reducing performance, the founder refused to accept the status quo of the day & instead pushed exhaust technology beyond common thinking. This led to many firsts in automotive exhaust science, as well as numerous patents protecting the various technologies used in Flowmaster products. With those developments, Flowmaster ushered in a revolution in automotive performance exhaust.
