Flowmaster manufactures a wide variety of Street Mufflers for a wide range of applications and sound choices. We make mufflers designed for trucks and cars with big block engines all the way to small 4 cylinder engines and everything in between.

 

And depending on your choice of sound, we have muffler series with mild , moderate, aggressive, and very aggressive sound. Check out our different series mufflers. If you don’t find what you are looking for or just unsure of your choices.

Super 10

Super 10 Series

Flowmaster’s new Super 10 series mufflers are so aggressive that we can’t even recommend them for use on street driven vehicles.


Super 44

Super 44 Series

The Super 44 delivers a powerful rich tone and is the most aggressive, deepest sounding, highest performing four-inch case street muffler ever built!


40 Series

40 Series Original

The muffler that started it all, the original 40 Series Muffler is an aggressive sounding street/strip muffler that delivers a powerful “Flowmaster Sound” you’ve heard so much about it.


Super 40 Delta Flow

Super 40 Series Delta Flow

Developed from our Top Ten race muffler lineup for use on the street and strip. Utilizing Delta Flow Technology, this muffler gives the best performance to higher horsepower vehicles.


40 Series Delta Flow

40 Series Delta Flow

Flowmaster’s Delta Flow 40 Series two chamber design incorporates Flowmaster’s patented Delta Flow technology. The “Delta” deflectors generate increased scavenging for better performance and reduced interior sound.


80 Series Cross Flow

80 Series Cross Flow

For True Dual exhaust performance where only a single exhaust system will fit such as is commonly found in classic Camaros and Firebirds, the 80 Series Cross-Flow Muffler fits transversely behind the rear axle and in front of the fuel tank, the OE placement.


50 Series HD

50 Series HD

The 50 Series HD Heavy Duty Muffler is appropriately named, a tough customer just like the trucks it was designed for. With 4.00-inch internal components and large case size, these mufflers help to significantly increase mileage, torque, and horsepower while greatly improving towing power acceleration.


HP-2

Hushpower HP-2

The HP-2 Performance Muffler is a real hot rodder’s muffler that delivers all the required benefits of a high performance street and race muffler, yet is small enough for street rod applications.
