I paid $900 for my ZJ. For that price you could buy 2.
Really it's not hard, you should do it yourself. Measure carefully, cut, bolt new pipe in loosely with the clamps at first, jostle it around to where you want it, and tighten up.

well final update guys: took it over to the dealer, they replaced the entire front pipe which had the cats in and it was completely covered under the 8 year 80,000 miles federal emissions warranty. Saved myself about 2k in parts and work! Note: the would not tell me about the warranty though, i had to find it out for myself and tell them about it.
