On a serious note, If you have a 2.5 inch exhaust the universal cat will work. it will just have to be welded straight in or you'll have to weld a set of flanges to the cat and your exhaust.

If not any universal will weld in place if it's the same diameter as your oem exhaust piping

Edit if it's a last resort you can have a 2.5 cat mated to a smaller exhaust but you'll be making an un-nessisary bulb in the system. not sure if that will cause any working problems with the cat though.

Downpipe?

Is this in an alltrac or a swap?

You'll be fine with that one if you're 2.5 the whole way. It'll just have to be welded in.

And you're good for emissions testing as well, that cat is sufficient.

Remember, it's not just the size, it's the capacity of the unit (though it's hard to find a cat that's too small for our engines).

i was planning on using a magnaflow cat and muffler, i just asked a few muffler shops which cat would work and give me a preformance gain they showed me and gave the part numbers also, a good place should be able to answer all your questions pretty easy even if you arent going to buy from them
