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 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 Muffler employs precision deflectors in the 2-chamber design that keep powerful sound mostly outside.

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

Notes

  • Flowmaster Super 40 Mufflers come in a variety of inlet/outlet configurations and sizes, shown above. Select the inlet/outlet diameter you need from the drop down at right.

"I just installed a super40 in place of my 2002 f150's 4.6 stock muffler. The sound is mean even with stock piping and I noticed a clear increase in low end torque. Also in-cab sound is barely louder then stock. I would recommend this muffler for any application."

"I originally had a series 70 muffler with my flowmaster exhaust. It took a little welding, but overall the 40 series sounds amazing, and there is definitely no power drawback from going down to a smaller muffler. Great product and get service."

1 of 2 people found the following review helpful.

"I really like the way this muffler sounds on the 4.0. It is very deep and aggressive. It has a nice throaty sound on acceleration and a nice gurgle at idle. It is loud though. It quiets down at cruising speeds, but is loud the rest of the time. I've heard louder, but this is relatively loud compared to a Flowmaster 50."

0 of 1 people found the following review helpful.

"This muffler was perfect for my 98 Tacoma and my own needs. It has the deep, tone I was after, but without being annoyingly loud and "God I wish I was cool, but I'm not, so I'll rev my 9 colored civic up to 6 grand before shifting into second through a school zone in hopes of raising my self-esteem" sounding. I have the muffler mounted mainly under the bed, and the interior noise is only a couple DB's louder than stock. It's great. I gained a lot of top end and some bottom end. It makes up for most of the shifting gaps. I'd definately purchase again. AutoAnything also provided excellent service; I'll look here first for all of my car needs."
