Yeah, it raises the car about 2 ft off the ground, which is good enough for doing exhaust, transmission, etc. The lift is called a Kwik-Lift. I picked it up used on Craigslist for $700.

I placed 3 orders on Amazon for the parts:
Y-Pipe - $184.99
Mid Pipe - $384.71
Axle Back - $319.99
Plus tax, free shipping.
Each part comes with new bolts and gaskets.
The bolts at the cats are pressed in studs. The 2 inside studs I had to cut shorter so I can hammer them out and clear the body of the cats to get them out. Outside ones hammered right out. Replaced them with the bolts provided.
Lube the rubber hangers with silicone spray to help with removal and installation. I also soaked all bolts with PB Blaster before unbolting at the cats. Pipes were rotted at both muffler flanges so the mufflers came out easy. Took the rest out in one piece.
