Rear o2 sensors information please! Hey everyone,
I'm looking to get LT 7/8 TSP Headers, but the real question I have is, how do the rear o2 sensors come into play?
I'm getting an ORY so CATS will be gone. I have read a lot of conflicting information on how the rear o2s function through multiple threads
(things like it effects everything but WOT, it doesn't effect the car at all, etc.)
Is it better to get rear o2s tuned out? Get o2 simulators?
What would YOU do?

Tune them out. There's no need for them. All they are is a tattle-tail that the cats are doing their job.
The fronts are where the WOT tuning comes into play.
**Disregard that last statement. Apparently I have had too many already this morning**

Incorrect on the fronts, At WOT the car goes into open loop and the oxygen sensors arent used. This is where tuning and widebands come into play. Although the front oxygen sensors are used for A/F corrections at almost everyother time the vehicle is running, except WOT.
I just ripped them out and had them tuned out. I keep them for spares incase the fronts ever go bad.
OP, yes get them tuned out.
Correct on the rears....
