Perfect fit
This pipe fit a 2015 Jeep JK perfectly and has a great throaty sound. Flowmaster has a video of the pipe installed. The only issue was with installing the hanger retainer, the hanger rod is close to the frame and the retainer it’s very tight. A socket and a pry bar worked well to get the clip on.

Sounds great
Mine came in good shape, welds were good. It doesn't sound like a fart can on a civic like some comments said. I had a cat back dual exhaust and it was louder than this pipe. It sounds good, deep tone at idle. Louder when you floor it but not bad at all. I recommend this pipe!

Fits 2016 JK and sounds great
Installed on a 16 Jeep Jk with the 3.6 It sounds nice. Not too loud but gives it a little noise with a nice tone. The only thing I didn’t like was it has a nice chrome tip on it, but the pipe is so short, it dumps out under the Jeep where you can’t see it. Not a big deal at all and is still worth it. It fit perfectly though…down to the exhaust hangers holding it. I would recommend.
