To settle the o2 argument it depends on the headers you bought. If you bought some like the bemmerbrake ones, they dont have cats, so you dont need the 2 post cat sensors. Im currently running with the just the pre-cat ones and it runs great. Do need to check my connections because I think either a bolt is loose or a gasket is bad

as far as I understand the pre cat 02s are the only ones that actually affect how the engine performs and the post cats are there strictly for emissions regulations and whatnot.
Mostarac how many miles do you have with no sensors in?

Once you start to remove the washer pump,sap, engine covers and cabin filter, splash guard and the brace you will understand how to remove the headers.

Trust me I didn't even use the pics. It's much easier then you think. Just make sure you have at least two full days because sometimes nuts don't come off or things take longer then planned. But when you get done you will understand thst it was a peace of cake and you had nothing to worry about.

Good luck and just pm me if you have any question I can try to walk you threw it.
