Will a catback exhaust system from a 94' fit on a 00' XJ?

I am looking into buying a catback exhaust system from another user here. However, before I go ahead an buy the exhaust, I want to make certain that it will fit on a 2000 XJ.

Any advice on what I should be looking for when purchasing the exhuast system? From what I understand, the cat is a year old and the pipe and muffler is not even 4 months old. What is included is the cat, the connecting pipe, the muffler, and tailpipe. Includes the hanger except for the rear.

Finally, what should I expect to pay to have the exhaust system installed? I don't claim to be much of a mechanic, so doing the work myself is probably out of the question.

The cat won't work since the '94 is OBDI and doesn't have an O2 sensor on the Cat.
