For over 25 years, the Flowmaster tone has been thundering through streets and on tracks around the world! Housed in two state-of-the-art facilities, Flowmaster uses premium materials along with extensive research and design to produce advanced, dyno-tuned exhaust systems and components that deliver power gains with an unmistakable sound.

Flowmaster Exhaust Systems

Some of the most distinct Flowmaster exhaust systems include the 40 Series and American Thunder mufflers, but there are plenty more choices—whether you want your ride to sound wild or mild, Flowmaster has the high performance exhaust parts you need.

Flowmaster History

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, Flowmaster's 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.

Flowmaster Products

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 legendary Flowmaster mufflers as well as 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.

Flowmatser Exhaust Systems

Depending on your choice of sound, there are 5 series of Flowmaster exhaust systems / kits designed for different vehicle applications that produce that distinct Flowmaster sound in mild, moderate, aggressive, and very aggressive tones, and widely available in aluminized or Stainless Steel construction.

Outlaw Series Exhaust Systems/Kits Outlaw Series Exhaust Systems/Kits feature race-bred components that ensure minimal restriction and only slight reduction on sound over open exhaust tubing on non-catalytic converter-equipped vehicles. With new vehicles featuring catalytic converters, Outlaw Systems can be compatible with regular street driving.

American Thunder Series The classic sound of a Flowmaster exhaust, the American Thunder Series features mufflers tuned to deliver more power, torque, throttle response and mileage. Best of all, these exhaust systems take sedate vehicles and deliver that great performance tone especially designed for muscle car and truck fans. American Thunder is the most authentic Flowmaster muffler sound we offer.

dBX series The newest laminar flow technology muffler, the dBX delivers the same fine attributes as the American Thunder Pro Series mufflers with a deep tone and great overall acceleration sound, but in a compact case perfect for smaller vehicles. The dBX features 304 stainless steel casings so they can be polished to a brilliant luster. If you want a truly track-tested, dyno-proven exhaust system that delivers a uniquely different tone, our dBX exhaust systems are the perfect fit.

Force 2 The Force ll Exhaust System is perfect for customers looking for some level of performance tone enhancement, but are concerned about installing an exhaust system that is too aggressive for daily street driving. The Force II exhaust systems commonly incorporate larger displacement mufflers and resonators to control overall sound, but increase the “performance impression” made by the vehicle. Our Force ll exhaust systems are a nice way to step up performance and tone on any vehicle.
