Am most likely purchasing a Gibson Swept Side Aluminized Cat-Back Exhaust System. I own a 2000, four door, 4.0

There are two model numbers for this Gibson system: 17200 (listed for 87 - 2000) and 17201 (listed for 2000-01) seeing as I own a 2000 I have two choices.

Does anyone know what one I want? and if so how difficult is the install?

 

can't say which model you want, I'd contact Gibson, I'm sure they can tell ya. A cat-back system's not bad if you've got a reciprocating saw(sawzall) and and angle grinder, getting the old stuff off's the hardest part, putting the new stuff on is usually pretty simple. While you're at it, you should go ahead and replace your stock cat with a high flow cat, Magnaflow makes good ones. Good luck with the install, make sure to wear eye protection while you're under there, and don't bother trying to unbolt anything, it will more than likely be rusted so bad it will be welded together, so just cut everything off with the sawzall and grinder.
