Which 02 sensor reads the a/f ratio and which one controls the CEL light, what I'm trying to get to is if they cna turn the one that reads the CEL light off so that the light doesn't come on for people with test pipes.

The front O2's (on the exhaust manifolds or headers) are actually wideband O2 sensors, and they feed the ECU data for AFR. The rear pair (in the rear of the cats) are emissions stuff to throw CELs for malfunctioning cats. Disabling them may be tricky on this car any other way than actually reflashing the ECU (like UpRev, etc).
