Cool cool, I'm guessing the "Y" pipe looks like a Y, I'm pretty sure I know what it is you're talking about. But what is the B pipe? Once again, im a n00b when it comes to exhaust.

I do have access to an air gun, but any idea on what size these bolts are?

The car is a parts car, if anyone needa any of the remaining exhaust pieces let me know!
The b-pipe is the pipe between the cat and the muffler. There should be 3 nuts that attach the b-pipe to the cat. Those should be 14mm nuts. Sometimes they get pretty rusted and have a tendency to round off. Spray the studs on the cat with some wd40, etc and let it soak for a few minutes. An impact gun will definitely make it easier to break the nuts loose. Also it may help to remove the exhaust from the rubber hangers and drop it down some to get to the top nut. At the y-pipe end, there are 2 bolts that connect the cat and y-pipe. The bolts are 14mm, the nuts on the ends of the bolts are 12mm.
