The hardest part is getting the old system off. The new system fit perfect and tucks up much higher on the jeep. According to the onboard computer the jeep gets 3 miles per gallon more but that's combined with a cold air intake also. It is just a little bit louder during acceleration, hardly noticeable at highway speeds. Highly recommended.
Nice and Mellow
Easy to install, great fit, nice welds, smooth bends. I got this for my 2017 JKU because I was looking for something that would make it sound a little meaner than a mini van, but I didn't want any drone. This exhaust delivered exactly that. You get a nice exhaust note when you are on the gas, but when cruising it's as quiet as stock. Not bnoxious at all, not "ricey", and quiet enough to off-road with. Best way I can describe it is this is how it should have come out of the factory.
