Price: $140.00
Pros: Quiet, quality, inexpensive, easy install.
Cons: Tailpipe angle wrong for my application
Recommended? Yes

Comments: Bought cat-back from SummitRacing for really cheap. Install was straight forward, but ended up having to spend $70 at muffler shop to have them fab up the tailpipe so it wasn't bent downward at an angle. Now the tailpipe comes straight out the back and is tucked up as tight as possible to the undercarriage without hitting the gas tank or shackle. The Dynomax factory angle just looks GOOFY and protrudes too much, but I understand they designed it that way to clear some bumper and hitch receiver configurations.

Sound is slightly sportier than stock, but overall it's real quiet which makes cruising with it easier on the ears than some kits. Next I will probably try the Flowmaster kit as I like a little deeper tone sometimes, but this is an inexpensive (well not for me) solution to a rusty old factory cat-back.

Good kit if the 10* sloped tailpipe angle wouldn't bother you any.

Pros: nice sound
Cons: tail pipe
Recommended? Yes

Comments: 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

Pros: Easy to install, relatively inexpensive, nice tone for the 4.0 especially at about 2500rpm
Cons: not loud at idle
Recommended? Yes

Comments: Excellent product for the money, and is fairly rust resistant (for now). I wish it was a little louder though, but it sounds great at about 2500 rpms in my xj. I got mine from summit, great guys to deal with and I would recommend buying from them anytime!
