The easiest way of getting the demon bolt out is, let someone else do it.
LTH's. Once I dropped the CBE. It took me about 45 minutes to do the right side cat and manifold as one piece. The left side took me about 5 hours. Mostly because of the manifold heat shield and the steering shaft. And all of the little screw and bolt ends sticking out to tear your hands to pieces.
Before you start with either the LTH's or test pipes.
REMOVE all of your O2 sensors to keep from destroying them from the vibrations.
