| i think there are 4 bolts (2 on each pipe) where the cat back bolts up to the exhaust pipes, and two screws (1 on each side of mufler) for the "hangers." its very ez to do, i unbolted my stock exhaust and put on new m3 exhaust all by myselt in my driveway with jack stands. i say "ez" but by myself it was pretty damn hard so if you have access to a lift and get one person to help you could prob take off old and put new on in about 10 min
