    Features

    Description

    Get the original aggressive Flowmaster sound that puts serious punch into your vehicle's presence and power. The Flowmaster Original 40 Series Muffler maximizes horsepower, torque and flow with its two-chamber design-the original two-chamber Flowmaster muffler.

    If the roaring sound of an engine is music to your ears, you'll love the Flowmaster 40 Series. Aggressive sound is maximized outside, while high-volume interior resonance lets you hear every push of the pedal. It's this total sound design that makes the Flowmaster 40 Series the centerpiece of many of Flowmaster's outstanding American Thunder Exhaust Systems.

    Ideal for early muscle cars, off-road rides and dual exhaust cruisers, the Flowmaster Original 40 boasts the quality construction you'd expect from Flowmaster. Each Flowmaster muffler is built with 16-gauge aluminized steel for corrosion resistance and fully mig-welded for maximum durability. Best yet, your Flowmaster Original 40 Series Muffler boasts a 3-year warranty.

    Best thing I can say about the Flowmaster is that it was made in the USA. Good product; easy install, affordable, got to me in reasonable amount of time. Thanks

    I have ran Flowmaster Mufflers for years and I love the sound of the Original 40 Series. The sound of the Original 40 Series Mufflers are a very aggressive tough sound that echoes the sound of performance.

    They have a very throaty sound, it's what a truck should sound like at all RPMs, I haven't tested the mpgs just yet but I believe it gained a few

    Great sound, very good quality! I've had these before, held up nicely. I got over 100k out of the last ones before I wrecked one 4wheeling. Highly recommend!!!
