Great, Almost Perfect

I purchased Kit2 with the baffled muffler to replace my OME on my 02 WJ. The bends in the tail were perfect, everything fit real tight and positioned well with the exception of the joint from the pipe out of the cat. Instead of compressing the pipe to match the same 2 1/4" I wish they would have flared it out to go over the existing pipe and this kit would be perfect. I tried the strap clamp like in the other review, but ended up going with a coupler and a couple of exhaust clamps. They give you plenty of wiggle room with the supplied pipe and tail. I cut mine down just about flush with the bumper. Sounds great and love how much lighter and better clearance this gives you over the original. Time will tell on the durability, but everything looks good. Thanks for doing so much for WJ's!

I bought this as "Kit 2" and installed it onto my 2004 WJ. The kit came with the muffler and tailpipe pictured, as well as a ~14" long straight section of pipe. You'll need that because the muffler is roughly 2/3rds as long as the stock muffler. I had some trouble fitting the pipes together due to OD/ID sizes and wound up using a butt joint clamp (not included) to join the straight pipe to the rear of the factory cat, but customer service through the process was excellent and the over-all price couldn't be beat. This kit was roughly the same price or cheaper than OE-style aftermarket replacement parts, and it sounds much better! The 4.7L tone sounds deep, isn't too loud, and there's no drone at cruising speeds. Durability is yet to be seen but workmanship is just as good as a Flowmaster. I dinged it one star because I had to supply the 3" long butt joint clamp myself, but otherwise I think you'll be happy with this!
