You're golden. Don't forget to have the emissions (AIR/EGR/Rear O2) knocked out when you have it tuned.

It shouldnt effect driveability at all, should it? The rears are just a guardian to make sure that your cats are working(and there). Shouldnt have any driveablility issues, right?

Correct, the computer makes NO adjustments to fuel/spark based on the rear O2's. Saying "Hey, turn on the SES light" is the only thing they can do.

Ok, good. I was gettin pretty confused! I wonder why we hear(or at least I have) all these horror stories about guys installing headers and then driving the car and it runs like **** for 2mon until they get their tune. They always say that the lack of O2's caused it and that you CAN, but you SHOULDNT run the car until the rear O2's are tuned out? Technically, you could connect your front O2's and just not even use sims or a tune on the rear. Just unplug them and tape the wiring up. Right? Of course you are going to have a light, but no 'limp mode' or anything.
