Take your stock header and cat off in one piece. This way, you don't have to fool with that demon bolt. When I did my FI LTH's. The right side only took about 1.5 hours to drop and install the headers. The driver side side took about 5 hours of cussing the heat shield that has to come out first before you can get to the nuts on the block. Once the bolts are removed. You have to turn the heat shield upside down to get it out. You also have to remove the steering shaft off of the rack and pinion to get the old header out, and install the new header. Have fun.
