Four o2 sensors?!?!?!
I have a 2000 T/A and i bought a pair of QTP headers, i did some reading and apperently i have 4 o2 sensors. My headers only came with two holes for the pair, what do i do with the other two o2 sensors? I am not running any cats.
Please someone clear up this confusion!

if you look at your car now, you'll see the front sensors going into the manifolds which are going to be replaced by the headers. so put those sensors into the headers when you install them and since you'll be running with no cats the sensors in the back don't matter. It will set of an SES light but the light can be tuned out. hope this helps

I'm not running any rear O2 sensors. I just got them tuned out. PM VinceTrifecta. For $100, he'll send you a hand-held flash tuner through the mail to tune out all the codes associated with removing the rear O2 sensors.

I would do that but it needs to pass NYS inspection. YES i know i will fail w/o cats, but i have someone who will only hook me up to the computer, as long as i pass that they have np with me having no cats, egr, and AIR.
Torque specs on the header bolts? Or should i just tighten them down? And use anit-siez or what?

I deleted the AIR codes and the rear O2 codes. I'll never fail emissions by getting hooked up to a scantool no matter what I do to the car.

That's the point of getting the O2's tuned out. The codes are permanently deleted from the PCM. That means you will never throw an SES light due to the headers, so when a scantool is hooked up, it doesn't detect the emissions system has been tampered with. The absolute best thing you can do is get the codes deleted. O2 simulators are not the best move as they are not 100%. The only thing that is 100% is to get the rear O2's tuned out.

And thanks for the advice earlyer in the month about the Corsa and QTP LTs!

lol thanks, don't mention it.
I used NGK TR-55's and MSD wires after my header install. There was nothing wrong with the stockers - 45,000 miles on Denso platinum plugs and they looked hardly used (at least I assume they were stock plugs, stock plugs are Denso's right?). The wires were in great shape, too. I just wanted an upgrade.
I forget what you gap TR-55's at.
