About:

Flowmaster offers you innovative exhaust products that get you noticed. From their two state-of-the-art facilities in California and Idaho, Flowmaster develops special exhaust parts that truly unleash your engine. If you want maximum performance, and maximum sound, a Flowmaster exhaust system is what you need.

If you want your exhaust to make noise, then Flowmaster has products for you. Some Flowmaster mufflers, like the Flowmaster Super 10 series, are incredibly loud and perfect for racing vehicles. The Flowmaster Super 44 and Super 10 are as loud as it gets, while on the other end of the spectrum, you might enjoy the rich, mellow sounds of the 70 Series or Super 50 series mufflers. The mufflers we carry cover a wide range of tones.

In addition to Flowmaster mufflers, we carry Flowmaster exhaust systems. If you’re into racing, you’ll enjoy the power and sound of the Flowmaster Outlaw series. Find custom-made exhaust kits for Toyota Tundra, Dodge Ram, Ford F150, and more.


Flowmaster offers incredible exhaust technology for DIY enthusiasts and professional racers alike. From their rich, aggressive tones, to their sleek looks, there’s plenty to like about Flowmaster. Shop our full selection of Flowmaster exhaust products today.

I just had a flowmaster exhaust system installed on my vehicle and it sounds amazing! A huge thank you to the guys over at H&H for their help with installation and purchasing! I will be back!
