What kind of exhaust are you putting on? Most aftermarket exhaust kits have a merger that allows it to fit over the factory y pipe. I believe stock size is 2.25 or 2.5

I had 2.5in welded on to the back of the stock shorty manifold and it looks a little bigger then the stock pipe. I would guess its 2.25in
...and the stock Y-Pipe has that disgusting flat slot on the driver side, get rid of that crap!
...and oh the joy once you put a new Y-Pipe on there and it starts beating the crap out of your under body. Then you'll know its time to do motor mounts, and have fun with that my friend.
