    Description

    When sound and power matter most for your high-horsepower ride, pick the muffler that built Flowmaster's legendary reputation and unique tone. The Flowmaster Super 40 Series Muffler runs deeper and more powerful than any other street muffler out there-even Flowmaster's famed American Thunder 40 Series.

    What's even more amazing about the Super 40 is the balance of deep Flowmaster tone and reduced interior resonance. Thanks to exclusive Gen II Delta Flow technology, the Flowmaster Super 40 Series Muffler employs precision deflectors in the 2-chamber design that keep powerful sound mostly outside.

    Also ideal for dual exhaust cruisers, Flowmaster Super 40 Mufflers boast the quality construction you 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 Super 40 Series Muffler comes with their original black case and boasts a 3-year warranty.

    I put this on my 2011 Ram 1500 and it put a throatier sound but not too much louder than stock. It is not that noticible in the cabin which is nice. I cannot tell you how much of a difference i felt as far as power due to other mods i installed but i love the sound of my truck now.

    Great Buy

    This muffler provides a nice low toned growl. On a scale on 1-10, as far as noise level. I give it a 6 with a straight pipe. I am very pleased with this muffler. I recommend it to people looking for a perfomance sounding muffler.
