I am finally converting to a dual header (vs. two into one). It just dawned on me that the dual header does not have an O2 sensor bung. My question is, is the 02 sensor required for anything above idle? I am a bit foggy on the utilization of the 02 Sensor.

If one IS required, which is the better pipe to get the readng from, the front rotor or rear?

No O2 sensor is required. By removing the sensor you'll force the car into open-loop at all times. At WOT the ECU isn't using the O2 sensor anyway. In open-loop you're running off a map and not using the feedback from the sensors anyway. Tune with you fuel pressure regulator.

Just what I suspected. Thanks Chris.
