Flowmaster

Want to give your car or pickup a deeper, more distinctive sound? Flowmaster is one of the best-known names in mufflers and exhaust systems for American cars, trucks and muscle cars. Here you’ll find mufflers, cat-back and axle-back systems and exhaust parts that give your engine a voice that suits you.

American exhaust sound with character

Flowmaster is an American brand known above all for its chambered mufflers. Instead of quieting the sound with sound-absorbing packing, many Flowmaster mufflers use chambers and baffles that shape the sound and give that characteristic deep V8 tone. The brand is now part of the Holley family and has long been a popular choice among owners of Mustang, Camaro, Challenger and American pickups, both for the street and the track.

Flowmaster’s key products

Mufflers are the core of the range, available in several series with different volume and character, from moderate and more subdued to aggressive. Super 44 and 40 Series are among the best known. For many popular models there are complete cat-back and axle-back systems, designed to fit the car using the original hangers. Flowmaster also offers tubing, tips and other exhaust parts for custom builds. See each product for vehicle fitment.

Frequently asked questions

How do I choose the right sound level?

Flowmaster groups many products by sound level, from mild to aggressive. Think about how much the car is used on long trips, as a very loud exhaust can cause more drone in the cabin at constant speed.

What’s the difference between cat-back and axle-back?

A cat-back system replaces the exhaust from the catalytic converter back, including pipes and mufflers. An axle-back system only replaces the section from the rear axle back, typically the rear mufflers and tips, and is often the easiest to install.
