well thats up to you.it will free up back pressure if you do get the hp.i was running mines on the stock one with no problem.

you can do either, it really makes no difference.

just add the nitrious the header does not make a differance what does though is the intake because you need the right amount of fuel/air in the engine

Header shouldnt make too much of a difference. And if you're worried about some HP gains from an exhaust..the most noticeable difference will be with I/H/AND Exhaust. Please...don't remove your cat though. Not only does it sound bad...but most emissions locale's WILL cite you for not havin one.
