I purchased a long breaker bar, the correct sockets, PB Blaster and an O2 sensor wrench. I've also been told to NOT use an impact wrench. Thanks for the suggestion of using PB Blaster several days in advance. I've never heard of anyone referring to the bolts as "demon bolts" before. Im not exactly looking forward to the install, but i wasnt concerend about it. Should I be worried?

My experience removing them was easier than removing the cat-back. Took about 4 hours with the proper tools at hand. When I swapped to test-pipes, it took like 3 hours with a crap selection of tools.

One thing that helped A LOT was removing the intakes and using a shitload of socket extensions and a swivel joint going in from the engine bay
