2011 Dodge Ram Big Horn
I installed this on my Dodge Ram and I love the sound. The only annoyance with this truck + the magnaflow was when the MDS kicked in on the truck. I thought this was going to be forever, but after the burn-in period, the sound is almost completely gone. This particular magnaflow is a direct fit for the dual exhaust Ram 1500. UPDATE: I forgot to update this sooner and it's been a year now...The exhaust has been on my truck now for over 10,000 miles and the sound is amazing. The truck no longer drones when the MDS kicks in...Somehow, the burn in period helps reduce this. I have bluetooth in my truck and I've never had anyone complain about cabin noise. Keep in mind that the Ram's exhaust pipes go all the way out the back, so you will not have as much noise as if you had a turndown pipe, for example.

sounds quiet just like I like it.
if your looking for a fair priced replacement muffler for Chevy 6.0l that isn't gonna cost 500 dollars then this is it. Some moron had hacked off the stock muffler and tried to get glass packs to work in its place and it sounded like crap, but the truck was in good shape so I bought it. Long story short the stock muffler was long gone so this is what I bought as a solution and its working really good. It does have this nice low rumble that makes it sound just a tad bit perkier than the other 6.0's in my area.

Just Right for my 5.0 F150
I wanted a deeper rumble and a little more volume than the stock exhaust on my F150. It was a bit louder than I expected but after driving with it for a week, I've gotten used to my truck sounding like a truck should sound. It has a nice balance, good tone when you hit the gas but not obnoxious. It sounds great accelerating, crusing 45-60 it quiets down to almost nothing. Anything above 70mph you can hear it in the background with the radio off, but with the radio or a conversation you can't hear it.

Magnaflow great quality and no interior drone!
Replaced FlowFx muffler case cracked after 2 months of use. Order the Magnaflow same size as other muffler. Bought some band clamps too no exhaust leaks and nice sound at start up, chill driving down the road sound. Nice aggressive sound at wide open throttle. Great replacement for anyone who doesn't want drone or too loud of an exhaust system. Running 2.5 inlet dual 2.5 outlets on 2022 Tacoma truck

Respectable Growl!
If you're looking for lovely low notes at normal driving and the sweet roar of the 6.4 Hemi when mashing the throttle, then this muffler is what you're looking for! Completely honest... it gave me an extra 1.5 mpg's, I legit didn't expect that much gain. It will seem a little quiet for the first several hundred miles, but after the break in is done, she will clean up nice and purr like a kitten. "The drone" inside the cab isn't terrible at all. I had both pipes "dual out" bent behind the rear passenger side wheel with a couple of 4 inch chrome tips.

Great product! Sounds good on a 6.0 Sierra
So far I am really happy with this muffler. I bought it to replace my dual chambered mufflers on my 02 sierra 6.0. I used it as a dual inlet, single outlet setup. I was concerned about drone at hiway rpm but thereโs nearly nothing. I was also wanting to quiet the truck down a little but not lose that rumble which this does perfectly. It looks great too. The only thing Iโm not sure of is how itโll hold up to salt on our Alberta roads in the winter but since itโs stainless it should be fine.

Nice Sound
Have it on my 6.2 GMC sounds nice, there is some drone

Not a exact fit extra modification needed
Love the sound. Not obnoxiously loud but enough throaty deep pitch on my ram to satisfy me. Not loud in cab either. Downside is they had to do some extra work to get it to fit so extra pipe was needed which meant a bigger price tag on the install. Still, worth it for me. Iโm happy.

Sounds amazing, better than I hoped
Sounds amazing , better than I hoped :) Great price too >> I had to pay extra to fabricate two hangers , and extend the outlet pipes as this muffler is shorter , still cheaper than buying the direct replacement fit ( although then it's a straight bolt on install in my own garage) >>

Louder than people make it out to be
Sounds great, a lot better tone than my flowmaster super 10. Just beware it is louder than people make it out to be. Most people seem to be putting these on newer vehicles which have great noise isolation in the cab. On my 03 Dakota which obviously doesn't have that, it's got a good bit of drone because it's not an 8 speed transmission meaning it runs at around 1500rpm on the road compared to 1100 or 1200 on newer vehicles.. meaning a louder engine. If you're expecting something slightly above stock sound output, this ain't it. This muffler started off quiet like I wanted to, and progressively got louder and louder during the break in stages.
