Berk HFCS Install tomorrow.. Need input.

[Proposed]

Greetings,
If you could read from the title already, I'm tackeling my HfC install and had a few questions. I know people have trouble getting to the cat to header bolts but I'm worried about how hard these "Demon bolts" are to really get off. I understand those are really the only thing that makes this install challenging. I know I'm going to have to take some of the intake tubing out to get to the bolts. Would my best bet be to get some bolt breaker etc to help free the bolts and make it easier. Also from experience how many of you broke tools trying to accomplish this task? I have a car lift to save me from the fear of being crushed.

Thanks for any and all comments!
