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.

"These were put on a 2008 Charger R/T They sound excellent IMO. Can be loud in the interior at times, so if you don't want that, then go with the 50's."

Awesome Purchase f150 4.6 super40

Posted on 12/18/2007 by Morgan G. - 2002 Ford F150 (Willington,CT)

"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."
