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.

"AAfter having had the 50 suv series with 3' piping on my Jeep WJ..I decided it was time to go louder and I did exactly that.. The Super 40 at first wasn't much louder, but let it burn in and you can really hear it bring your car to life..Loud enough for anyone to get noticed.. Really liked it"

"I puchased the muffler a couple of weeks ago and after the installation, what a difference. The sound is awesome. the lack of back pressure has given me alittle better performance, especially off the line. My 05 Ford f_150 FX4 now with this muffler and sound is the complete package. The compliments just keep coming from everyone that sees & hears my truck. Thanks for the upgrade to my happiness. Will purchase again, if needed."

"SIMPLY REPLACED THE STOCK MUFFLER WITH THE FLOWMASTER SOUNDS TOUGH BUT INS'T OVERLY LOUD, SEEMS TO HAVE A BIT MORE RESPONSE, HAVEN'T CHECK FUEL ECONOMY. WELL WORTH THE INVESTMENT JUST FOR THE NICE RUMBLE!! ONE LAST THING BE SURE AND INSTALL IT CORRECTLY MY MUFFLER CAME FROM THE FACTORY WITH THE INLET TAPE ON THE WRONG END LOOK FOR THE STAMP IN THE METAL THAT SAYS INLET."
