If your looking to add that throaty V8 diesel sound this muffler delete is perfect and Inexpensive. Only complaint It came a little lopsided. Both ends didn’t fit perfectly. Had to use a dead blow hammer and open it up on one side and push it in the other side. Once more circular it slid on with a little WD. I wasn’t sure what to expect going from the Mbrp muffler. It didn’t get much louder until higher end. I can hear the turbo whistle much more out the exhaust now. I have WW2 / injectors/ php hydra and a few other upgrades. For the price it’s great

One of the best purchases I've made for my truck, sounds absolutely incredible. Would buy again.

If you’re thinking this pipe might make your truck too loud, don’t. There is a slight difference in sound over the mbrp muffler, but most of what it muffled is turbo noise. My cclb sounds about the same inside the cab, but when you roll the windows down it’s all turbo whistle. Sounds great. Delete your muffler. You won’t regret it.

I’ve done injectors hpop rebuild fuel mods oil mods and a lot of other things I can’t even remember. I got ahold of a real diesel mechanic who did the research and sent me to Riffraff. I ordered bocoos of stuff from them. I talked to Clay at least 3 times and it was like visiting with an old friend. We changed to different tuner with dial on the dash and I’ve got the best ride with awesome power and I mean real power!!! 2001Excursion 7.3. I’ve been pulling disaster relief trailers all over the east coast since last hurricane season and headed out this weekend for another trip. You bet I’m keeping Riffraff’s number.

Was looking around for a piece of pipe, nobody had anything in town. Ordered this, came in a couple days later and had it on in about two hours. Perfect fit! As always the Riff Raff crew knows what we’re looking for.

I have the banks 4inch system, I removed the monster muffler and found that they are a clean thru muffler, installed this anyways. great fit no adjustments needed

Looks well made arrived in timely manor but alas will not fit stock obs 3.5" with out major mods even with Banks stinger plus exhaust

Product was an exact perfict fit to delete my muffler, and Riffraff's excellent customer service got it here two days earlier than it was even supposed to. This is absolutely the best place to order any parts from, hands down. Thanks, Riffraff!

Love the product and sound. Made my truck go from mundane to insane!
