Advertised as a stainless muffler and even had the same part number for the stainless muffler but over paided for and got the regular steel one. Didn't realize until.it was installed and drove for a few days, the welds are already rusting, plus a magnet sticks to it which stainless is not magnetic

Installed on my 2023 Ram Laramie Sport w/HEMI e-Torque. It has a great powerful sound with very little inside drone. This muffler is made for the HEMI Engine. They should have it installed from the factory.

I added this to my 2020 Ram 2500. I had to take it to a muffler shop because they have to weld hangers on it for it to fit. It was easy though, only cost about 60 dollars to have it installed and only took about 20 minutes. This gives the 6.4l a more truck sound with some decent low end sounds and rumble and a little loud when you stomp on it. Otherwise, when cruising it isn't too loud. I pull a 30' camper and it still sounds great while towing without being overly loud. If you want a little better sound, while still not annoying the neighbors, this is the muffler for you.

Good muffler, well constructed and has a very throaty sound. Louder than the magnaflow I had but quieter than the Borla I also had. It's still a little loud for me but may not be for others. Minimal drone with headers and a high flow cat on a 2012 Silverado 6.2L.

When replacing original with this muffler make sure you have a welder and have material to lengthen either the tail pipe or intermediate pipe. This is not a perfect replacement. Other then that good noise and I have all the material and tools to do the swap so not bad for me

Installed in a 2018 Ram 2500 6.4 hemi. Nice quiet tone but a little more throaty than stock. Also installed with a cold air intake and now there is some throttle response at the low end. Definitely made a nice improvement to stock. Sound great when you get into the throttle but nice and mellow at cruising speed. Just what the truck should sound and run like from the factory.

I put this muffler on a 2013 Silverado 2500HD with the 6.0 Vortec motor. I was going to get the 50 Big Block series but Flowmaster calls it "the quietest muffler we make" and I wanted to at least hear the exhaust. Well, as far as Flowmaster goes, a little dab will do ya. This 50 HD is quite noticeable. The sound is a deep rumble and it sounds good. My issue is the significant drone in the cab that happens between 1600 and 2100 rpms. This happens to be prime cruising speed (65-75 mph) in my truck.Flowmaster makes a great product but be sure you know what sound you're looking for; they can be aggressive. Ask a muffler shop tech for advice.

I expected a direct fit but had to have a reducer made for the inlet side because it was a 1/2" larger in diameter than my stock exhaust pipeOther than that....great sound and improved gas mileage
