the stock cats i think are 3" in/2.25" out, at least for my car it was, and I have a 2001. the exhaust shop just welded the 3" pipe around the outside of the 2.25" outlet on my stock cat. and re-attached all the emissions stuff. I'm sure they can make any cat w/ up to 3" outlet fit on a 3" exhaust.

If you've got the cash, then I'd say get a 3" cat.

Any exhaust shop worth it's salt will be able to deal with whatever size pipes you already have.
