This is the most "aggressive" sounding street/strip muffler that Flowmaster offers. If you're looking for attention, this one will get you noticed. The standard 40 series has an "aggressive rumble" and will generally resonate inside the vehicle around 1800-2000 rpm’s, and again at 2400-2600 rpm’s.

The Super 40 is our latest development utilizing "Gen II Delta Flow" technology. This gets you the best of both worlds of Sound and Performance. The Super 40 has that "deep powerful" sound of the original 40 series but with all the benefits of performance and low interior resonance from the "Delta Flow technology."

Using the technology seen in our larger Super 40™ mufflers, the Super 44™ delivers a rich deep tone, an improved flow path radius, optimum internal flow and sound control, all created with Flowmaster’s Delta Flow® technology. It is the most aggressive, deepest sounding, highest performing four inch case street muffler we’ve ever built!

This two chamber design incorporates Flowmasters patented "Delta Flow" technology. The "Delta" deflectors result in increased scavenging for better performance and reduced interior resonance over the standard 40 series with a nice growl outside the vehicle. Sounds great on late model performance cars with catalytic converters.

The 50 series "Big Block" muffler is our largest muffler for tow vehicles, trucks, large Sport utilities and Recreational Vehicles. This muffler is made for more than just big cubic inch engine applications. It has a very large H-Chamber to reduce interior resonance in large cab areas of vehicles and enough case volume to handle engines under heavy loads.

This is the latest design of the 50 series muffler that utilizes Flowmasters patented "Delta Flow" technology along with an "H-Chamber" to eliminate most all interior resonance and still have that famous Flowmaster sound outside the vehicle.

Another addition to Flowmaster's product line is our 50 Series™ H.D. muffler. It is Designed primarily for today's higher horsepower trucks such as the Dodge HEMI. This muffler will perform well on various vehicles when a deeper, more aggressive tone is desired. This new muffler features a 4.00-inch internal design, which is ideal for trucks with modified engines.

The SUV/Performance muffler is a larger version of Flowmasters 50 Series Delta Flow muffler and is specially designed for trucks, light SUVs and high horsepower vehicles. The larger H-chamber reduces interior resonance to a minimum.

The 60 Series incorporates Flowmasters patented "Delta Flow" technology to produce a nice mellow sound for your sport compact car & Truck. A larger diameter tailpipe will create a deeper tone both inside and outside the vehicle.

The 70 Series "Big Block II" uses a large case for increased volume and added sound reduction that will still fit many applications that our 50 series "Big Block/HD" muffler won't fit. It utilizes Flowmaster's patented "Delta Flow" technology for maximum efficiency and reduction of interior resonance. Use on high performance street cars, trucks, SUV's, RVs and tow vehicles.

The 80 Series is designed for applications where the muffler must be mounted transversely (cross-flow) behind the rearend. It provides an aggressive muscle car sound both inside and outside the vehicle. A replacement for early and late model Camaros & Firebirds.

The Hushpower II incorporates "Jet Laminar technology" together with Flowmasters sound chamber designs to give a sweet rumble reminiscent to that mellow 1950's tone in a very compact and presentable case.
