Another up-date.
Got my FI exhaust on. It took longer to jack the Z up, then to remove the exhaust from the cats back. It was about 45 minutes to remove it. The right side header took another 1 hr to 1.5 hrs. to remove the stock header and cat, and to mount the FI header. The left side header was a royal pain in the a$$! That was about 5 hrs of mother-!@#$%^ the heat-shield. You have to unbolt it, turn it up side down. Then fight to remove the F@#$% piece. Once out. It becomes a little easier. Notice, I said alittle easier, not by much. I've been working on HP cars, trucks and motorcycles my whole life. This left side is tight to get your hands into. I found it easier to tighten some bolts from under the car. My hands and arms still have the battles scares on them.
