Description

When sound and power matters are at the top of your list for your high-horsepower ride, pick the muffler that built Flowmaster’s legendary reputation and famous tone. The Flowmaster Super 40 Muffler runs deeper and stronger 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 its ability to deliver 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 most of its powerful sound outside.

Also perfect for dual exhaust cruisers, the Flowmaster Super 40 Muffler provides 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 1-year warranty.

"I have a 2008 Ram 1500 with the 4.7L engine. I was skeptical about putting the flowmaster on since I didn't have the hemi, but I'm glad I did. Muffler sounds great and gives me that deep throaty sound I was looking for. Will definitely buy flowmaster in the future and autoanything's service has been excellent."

"When i had the flowmaster muffler installed i noticed a huge increase in horsepower and my gas mileage went up to 17-18 around town. This muffler gives the 318 a nice throaty sound and is not loud from the inside of the truck. I would totally buy this muffler again its well worth it"

"Overall it is a good product. I went for a straight muffler swap and ran into some problems. The muffler is painted so be sure to grind off paint in order to get a good weld. Didnt fit correctly so ran into a little extra work in the install but that was probably my fault. Also it is not as loud as I would have expected but I also only have single exhaust. Sounds great and has good tone with no drone. Not loud in the cab at all, even with the windows down. Good product and I would recommend it to others"
