Just take it to the nearest hole in the wall muffler shop and they will take care of the whole thing. Costs like 20 bucks and will save a few brain cells. My guess though would be 2.25 id pipe, but Im really not too sure about that.

i have a 91 with a 3.1 in it if you are going to cut the cat off just use a 2 1/8 inch pipe because your stock pipe is 2 inch and that will fit snug over it.
