Default Cat Delete

I'm not 100% sure this post is in the right thread but I'm going for it. If I were to delete my cats and rear o2 sensors, and have the codes removed from the computer, would it still pass a obd-2 emission scan. Where I live they don't use the tailpipe sniffer or visual inspection. Basically I am wondering if it would still pass emissions if the o2 sensor codes were removed from the computer. Also would this work the same for egr and air deletes?

It will so long as the readiness monitors are set to ready before the codes are deleted.
