Default Headers and O2 Sensors ???

Just installed a set of Kooks headers W/O cats and I have a question about the O2 sensors. Am I supposed to remove the front sensors completely and put the rear sensors in the front locations? I plan on doing a quick "safe" header tune with either a DiabloSport Predator or with HP Tuners this wekend. I need to know before I put the car back on the grond.

What are you guys doing?

Yes. Remove the front O2's. Block off the rear O2 bungs, and install the rear O2's in the front positions....left to left..right to right. You will need adapters to mate the rear O2 connectors to the front O2 harness.

When you do this you hook up the wires that went to the fronts and program out the rear wires right?

Using the adapters, you connect the rear O2 plugs(now installed in the front positions) to the front O2 harness. Yes, the rears are tuned out.

Sweet. I called LG just in time to get them ordered. I was told to NOT cross the (rear) harnesses when reinstalling them to the front locations. Turn off the rear O2's with a tuner and hit the road.
