            pipe was too long

            I ordered this kit and the pipe right after the muffler was too long. I had to cut the piece about an inch and a half. Also one of the female ends was not expanded enough so I had to rent a pipe expansion tool to complete the installation. I would give it a higher rating if the installation went smoother. After the installation, the exhaust sounds great.

            Easy to Install

            The system really tucks into the under body. The instructions are easy to follow. I did need to bend the edge of the heat shielding a little. When aligning the sections make sure the support pins are horizontal. The sound is like James Bond's Spectre sports car.

            Great Exhaust

            The exhaust fit perfectly on the 2 door JL Sport. It is not overly loud and has an aggressive sound. Compared to stock, this exhaust provides much better ground clearance. The tip of the exhaust is about flush with the bottom of the JL Sport stock bumper. The install was easy, with the hardest part being the removal of the stock exhaust. Specifically the rubber hangers. Using a hanger tool would have made the install much easier. Overall, I would highly recommend this exhaust.

            Great quality and great sounding product! The tones work very well with the new 8-speed automatic! My only gripe is that the extension for the four-door is about a half-inch too long and had to be shortened ....

            Excellent Exhaust, interesting install.

            This is exactly what I wanted in an exhaust! I'm gained additional ground clearance since the OEM muffler is no longer hanging low under the rear of the Jeep, and the sound of this muffler is just impressive to say the least. The install was a bit more challenging than I expected, as the extension pipe to the over axle pipe seemed about 13-15 mm too long. Once that was cut down, everything lined up perfectly. I will also say the rubber hangers on the JL seem a bit more beefy from what the older models had, so using a hanger tool made this install go much much easier.

            Excellent exhaust system!

            I just installed this exhaust system on my JLUR last weekend and love it! The stainless steel quality, the weight savings, the added clearance and of course the sound are all great! One of my daughters said it sounds like a sports car! Putting the new exhaust on was a piece of cake, although you may want a second set of hands to properly place the first two parts. Getting the old exhaust out was far more difficult. The biggest recommendation to make it easier is to have a set of exhaust hanger pliers. Also make sure you have a good floor jack to lift the front so you can clear the old exhaust when you remove it. I don't know how an exhaust can make a Jeep more fun to drive, but it does!
