Question before I buy

[jpalamar]

I'm not new to the GM world. I had a friend tune my 04 GTO and I helped a few years back. I have a general idea where to start and feel I can figure the majority of the rest out.

My current car is a 2003 Z06. Only mods are Corsa Xtreme exhaust (x-pipe and mufflers). I'm looking to pick up a set of headers from Texas Speed. They are going to be catless and also remove my AIR system.

My question is I know I can disable my rear O2s and the sensor will not report a CEL but will also not be ready. I'm allowed 1 sensor not ready for emissions in PA. What can I do about my air system? Is there a way to not throw a code AND have the sensors ready?

Thanks in advance.

Just because you disabled the rear o2's does not mean it cancels out the readiness monitor. I disabled my one downstream o2 and the other 3 are still active and the o2 monitor does go to a READY state. And this is on my 2002 S10 V8.
