Helped quiet down triton v10
Installed a flowmaster 40 to replace the old rotted muffler on a triton v10 motorhome, ended up being the worst sounding exhaust ive ever heard in my life. Ordered this flow fx to install before the 40, helped quiet down the system and make the note bearable.

Excellent product! 5.7L Hemi sounds fantastic with it!
Muffler sounds great! I had my truck essentially straight piped with the factory catalytic converters on. I couldn’t stand the droning in the cabin and was looking for an inexpensive but effective muffler. This muffler helped reduce the cabin noise significantly and the truck still sounds great. I would highly recommend this product!

I got 2016 Ram v6. I had super 44 on it. Sounded horrible when accelerating, like one of those low hondas kids drive. This muffler went on like a breeze. Sounds bit quiter, but not alot. Gonna add a resonator after the muffler and see what that does. Nice looking finish to it though lol.

Great sound, easy install
With a couple SS pipe segments, I replaced the factory muffler with this pleasant sound, and for about half the price of the stock replacement.

Sounds good but not too aggressive
Sounds good if you’re looking for a little louder than stock. Not too loud and no drone Just gives a deeper tone. Looks good also. I used it on a 95 Chevy dually with a 454 single 3 inch exhaust. At About $50 is a great price. Can’t buy stock for that anymore

Super happy with this. Sounds awesome. Price is better than anywhere. My neighbors might not be as happy. But it's so much quieter than my old exhaust. Has that cool rumble and no drone on the hwy. My person can actually talk to me when I'm driving........(as if I'm listening lol.)

Sounds great. A bit quieter than I was hoping but I'm sure it'll get louder over the years. Running with cats and no resonators on my 2010 Tahoe. Absolutely no drone on the highway is a major improvement from my old thrush welded

Fair price and work great. Truck was obnoxiously loud thanks to my husband is still being 17 mentally but now it sounds good with just a bit of noise so we’re both happy.

Had to cut the ends off and re-weld new 3 inch pipes because of how badly crunched in the ends were
