Biggest issue I have with that side is torque, there is no way to torque the header bolts to spec when it goes back on, you have to educated guess it. If it is a stock header it's not that bad, I usually disconnect the downpipe at the most convinient place..in my case I have the hooker dual exhaust and there is a junction about halfway toward the back of the car....four bolts and it falls off. Once the downpipe is free you can manuver it out of the way. Up-pipe and crossover obviously come off, once these items are clear you can access all the bolts directly or through the fender well. Then it's just a matter of getting it into a position where it can be pulled out. Be sure to disconnect the battery, if you don't and that downpipe or header catch's the starter your gonna wish you had.....
