Some of the states changed their guidelines and now need all system in check to pass. When before 1 system could be not ready.
So NY is still 1. If I remember correctly, before I cleared my codes after fixing my O2s, the only one that was not ready was O2 Sensor (Cat monitoring seemed to go ready). Nothing on the car has changed other than swapping in new front O2s. And yes it's a full exhaust.
