Ya'll the rear (cat) o2's have no effect on how your car runs. 0000000!!!! All a rear o2 does is tell your PCM a cat is bad. That is its only purpose.The front o2's talk to to the PCM to set A/F ratio etc.......My rears are deleted because headers changes the readings and MAY set a light but in NO way affects performance....
