    • Easy install, and sounds very agressive
Style: Base Product
The hardest part was wrestling the exhaust pipes out of the hangers and factory muffler. Once that’s done, the Flowmaster can be installed in maybe 10 minutes or less. Goes back together very easy. I think it sounds very loud. If you don’t want loud, you should try FlowFX by Flowmaster

    • Sleek Exhaust, Mean Sound...
Style: Base Product
So every morning when I remote start my Ram and all my wife's pictures start to shake and rattle on the living room wall and my baby wakes up from a dead sleep crying her eyes out... well, I smile. Let's start with the removal of the old exhaust: this is an absolute terrible process even with PB buster and your semi-capable wife helping you. I live in Michigan and it's a 2013 ram, which had undoubtedly started to show signs of rust and wear, so maybe if you live somewhere less abrasive then you'll have an easier time removing the stock muffler. It took at least an hour to get the old one off. It's a 15mm socket (medium to deep size). Installing the new exhaust probably took 10 minutes and everything slid together easily. In reality, once the exhaust settles down from a cold start it isn't that loud at all. I wanted an exhaust that you could hear but not one that make's people look and say "what an A-hole". I think this is that exhaust. At idle it isn't even noticeable, when you step on it, you can hear it. As for the in-cab experience: it sort of reminds me of someone who's driving around with a grizzly bear and pissed off gorilla in the bed of their truck. I don't really care what other people think, I just wanted a nice sounding exhaust for myself, and this flowmaster provides just that. If you want a real mean sound I would recommend going with the full cat-back outlaw system with the resonaters deleted. I was thinking my wife wouldn't even want to drive the truck after I put this on--which was my hope--but she said it wasn't that bad, and I think she enjoys driving it as much as me. I don't really notice any "drone" per se, but it is loud at 70mph cruising speed, but what do you expect; it's tolerable though. ... show more

Installed in a little over an hour... It would have been much quicker had I used a lift. The worst part was getting the old muffler off, but it wasn't too bad... Pro tip! Soak the old clamps down with an oil penetrator to make life easier... Also, I'd say it's worth it to drop the tips off the rear hangers to give yourself room to back the muffler off of the 3 inch pipe. I used a rubber mallet to knock it rearward, and it worked amazingly well. This exhaust sounds great!... there's no other way to describe it! It's unreal how much a difference just a muffler alone makes on a 5.7L Hemi. I recommend this kit, 10/10 from me! Personally I believe these mufflers should come on the Rams stock from the factory. ... show more

    • Money well spent.

Flowmaster lives up to its name. Producing a great rich deep growl to my Ram Hemi. One thing I appreciate is that it is not overly loud and annoying . It gave me the sound that I was trying to achieve…

    • Pretty nice muffler...
Style: Base Product
Super nice quality. I'm glad I picked this over the "American Thunder". This really isn't that loud, but I'm a "hotrodder". By just switching the muffler, I mean you still have the catalytic converters and the resonators. They are not mufflers per se, but do muffle the exhaust also. If an exhaust system made less sound then this, there would be no reason to even change anything (in my opinion), just leave the exhaust stock. Everything was pretty much a perfect fit, no twisting or "adjusting", just seemed to work pretty nice. Sounds great. Initially my plan was to not destroy the stock muffler in case I wanted to put it back on for some reason. That plan went pretty well right up until the end. I loosened the 3 original band clamps and the pipes came loose okay. But getting the getting the stock muffler all the way out didn't seem to work that great. I got the front pipe slid out, but couldn't get the back 2 (tail pipes) slid back far enough to come out. I wrestled with them for a bit before getting disgusted and just sawing the back two nipples off of the stock muffler. It was just hard to get any leverage to wrestle the back pipes. Maybe if I would have had a helper and some patience, I would have salvaged it, but it just didn't go that way. Overall, really happy with everything... !! ... show more

    • Easy installation, great sound.
Style: Base Product
The only downside was that 2 of the opening were a bit dented. I had to pound them back into round so I could install it and not have any leaks. I assume it was from shipping as there wasn't much packing material. It was direct fit and easy to put in. I'd recommend soaking all the original hangers in penetrating oil and let it sit a bit before installation. Good sound, but not over the top loud with stock resonators still installed. ... show more

I was heavily debating getting the Carven Competitor exhaust instead of Flowmaster Outlaw. But for $272 shipped to Alaska off Amazon and saving $130+, I decided to go with the Outlaw. First off, the videos on YouTube DO NOT do this exhaust justice! It sounds so much better in person. Very happy with this exhaust. Second, the stock exhaust has cut outs on the inlet and outlet pipes that line up with indexing points and the tailpipes and where the exhaust comes down from the engine. Flowmaster has these same cutouts to ensure a proper fit, Carven does not have these cutouts. Third, it was a very simple install once you figure out how to wiggle the driver side tailpipe out (hint: wiggle it from the back by the bumper) the passenger side tailpipe is very simple to wiggle out (also use a lubricant like WD-40 on the rubber brackets so they move freely). Took me all but an hour to install. No drone, not excessively loud until you step on it, great deep gnarly sound. A lot of people say the clamps that come with it are garbage and create exhaust leaks, I have not had that issue. I did buy a set of Walker and Dynomax Lap Clamps just in case. Can’t go wrong with this exhaust for $272. ... show more

Love the extra horsepower and torque. Increased fuel economy and of course the aggressive mean sound.
