exhaust help!!

[dshultz88]

I own a 99 v6 and I recently bought a MAC catback exhaust system. I was taking off the stock exhaust, and one of the nuts that connects to the y pipe is rusted and completely stripped. I got the other one off fine. Any suggestions on getting that other nut off?

Sawzall...something you can cut it off with. Only way I see getting it off.
