I decided to install this kit when I had to put a new catalytic converter in.
the install went easy, but my gripe lays in the tailpipe. It was pre-bent with a so-so fit. If you manage to get the hump to clear the heatshield on the body tub (without banging and rattling) the tailpipe hangs so low it hits EVERYTHING offroad and the tip sticks out real far, my first offroad trip I nearly ripped the back of the muffler out several times.
so out came the sawzall, I cut the tip off and trimmed the remaining pipe for higher clearance, but it still hangs low, I've bent the rear hanger to get it up as high as I could before the hump starts to make contact with the body tub heatshield and make loads of rattles from it.
the more permanent way to fix it would be to take it to an exhaust shop and have them bend the tail pipe a bit more to place the exit higher up.
As for the sound, it adds a nice note to the 4 banger, not absolute ricey, but notably "stronger" without being overkill, I find it the perfect muffler for those looking to add subtle spice to their stock-ness
