    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.

    Well I decided to get this muffler for my 2000 Silverado step-side. The truck just didn't have any sound whatsoever. The muffler was a good price and the sound is really awesome. I did notice that it took a few days for them to really come to there own so to speak. The sound after a few days is great and not too loud. Now I ordered the 3" inlet/outlet and wished I had ordered the 2 3/4" because I had to go to Autozone and but fittings for the ends but no biggie. Overall it's a great melody and hear. Go get one you won't be dissappointed.

    There's nothing like cruz-in with the "FLOW"....
