Company Overview

Thirty years ago, 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, their 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, as well as many patents protecting the various technologies used in Flowmaster products. With those developments, Flowmaster ushered in a revolution in automotive performance exhaust.

Deep into the 21st Century, Flowmaster has continued to embrace new technologies in the automotive world, while continuing to deliver outstanding sound and performance benefits to all types of vehicles from both their legendary chambered mufflers as well as their laminar flow designs. From Flowmaster's state-of-the- art Research and Development Center, new products and applications are regularly introduced, from mufflers to high flow catalytic converters, high-performance headers and a full line of carefully engineered bolt- on exhaust systems. As always, all Flowmaster mufflers and exhaust systems are developed and manufactured only in the USA.
