Installing a X-pipe tomorrow...?

+1 on the PB blaster. That sh1t is amaZAzing. You'll also need a long ass extension for your socket wrench (about a foot or longer) and a swivel for the socket. Do the passenger side first because it's a BITCH.:bang:
 
I would get a buddy to help you with it. It will be so much easier. A couple jacks will help in keeping your catback in place when you unbolt the factory h-pipe. Just put them under your mufflers when you have the car on jack stands.
