Usually the tune required to get rid of the check engine light shuts off the rear o2's they exist only to double check that the front ones are working correctly and making the necessary adjustments to reduce emissions. By getting rid of your cats they are pointless anyways. Most headers have them just installed and non functioning. Some remove them altogether.
