Flo pro direct fit muffler for 5.7

[Tom Williams]

Anyone try this muffler? I’m looking for a slight rumble with no drone. The video seemed to fit the bill, just want some reviews. Thanks all!

I switched to this about a year ago. I love it, absolutely no drone. Sounds a lot deeper and throatier than stock, very quiet cruising. I believe it was flo pro #2511. It is almost as big as the stock muffler, but you can see thru the flo pro when you look into the inlet.

For no drone, stay away from the Flo Pro Twisters. Obviously a different muffler than 2511, but the Twisters are a knock off of the Moroso spiral flow mufflers.

I had two 12” twisters with an H pipe on my 2004 RCSB Hemi. No back pressure, loud hemi fart between 1st and 2nd at WOT, drone was awful. Ended up swapping them for two Flowmaster super 44’s.
