I installed this on my 2016 JKU. The install was pretty easy, a perfect fit. I really like how it tucks up under the body. Nothing hanging down to hit rocks, etc. The sound is terrible. I didn't expect a V8 rumble, but I also didn't expect it to sound like an '89 Honda Civic with a giant can hanging out the back. It is embarrassing to accelerate and it drones obnoxiously between 2k and 3k RPMs. After reading online advice, I added the stock resonator back into the mix and the sound is much better, lower and softer, just a little louder than stock and no droning. If you want your Jeep to sound like a model airplane, this is the system for you. If you just want to get rid of the giant stock muffler and gain some clearance, while improving the sound, perhaps you should look elsewhere or plan to use the stock resonator.

Install went way faster than the removal of the factory system. The first tube needs the factory hanger taken off the vehicle Or you’ll spend an hour trying to fit properly. The rest can stay. Finished product looks great and sounds deep and throaty. Almost V8’ish. Doesn’t sound like boy racer exhaust. Recommend this system to wheelers especially since it’s a high tuck system.

I installed a MF dual exhaust on my 2016 Jeep Wrangler a couple of years ago and it added a nice "rumble" sound that I loved. Fast forward two years and my Jeep going from a pavement princess to rock crawler. Both pipes on the MF muffler were pancaked and since I am about to do The Rubicon Trail, I wanted something up out of the way. A friend and I installed this system within an hour and a half and the longest part was getting the old muffler and piping off (previous muffler had been welded on). The "rumble" is only slightly louder than my previous muffler but I don't mind because it doesn't "scream" or vibrate my teeth when driving at higher RPM's. I also added HD "Roadformer 2.5" lap joints, but had to uninstall the two on either side of the muffler because they wouldn't cinch down solid enough. We also had to move the piping around to keep it from hitting against the frame. Solid install now and sounds awesome!!

Free flowing exhaust. Loud. Not bad around town if you stay out of the throttle too hard. Drones at freeway speed on the verge of uncomfortable. I bought it knowing all this, but took the chance. I may back this up with an after market resonator to tone it back down a bit. Very likely to piss of the neighbors, but nobody really likes them anyway.

I bought this for my Jeep 17 jk wrangler. After watching all these videos and reviews I thought this was the one. I was wrong! I wouldn’t waste your money it makes your Jeep sound like a rice burner after having it on for over 3 weeks I’m already looking for something else with a deeper tone. I will Say I love how it’s tucked up against the body from harms way. Just don’t like the sound just my opinion.

Not for everyone and it has a unique tone but it did add throttle response and seemingly some Hp....

I ripped the two factory rubber hangers and dented my exhaust. so I was looking around for exhausts on YouTube guy put up a video of this one. He said he got it on Amazon so I picked one up. Very easy install I love the sound not to loud but has a good tone. I also love how much it opens the rear end you can't see the exhaust at all now I need to get a nice diff cover because that's all you see when you look at the back of the jeep
