Nope on the scanner part, YOur car has to go through drive cycle before the emmisions place can test it. If you do delete them all an go up there there test will say system not ready.

Mine passed two days ago with no cats. I have the o2 sims...and a tune... BUT A buddy of mine just plugged the back o2 bungs and tied the rear o2 sensors to the frame... To my knowledge, the rear o2 sensors just need to read something different then the front o2s...

hmmm interesting ....thanks

The sole purpose of the downsteam O2 sensors is to monitor Catalytic Converter efficiency and relay it to the ECM.The upstream O2 sensors are for the ECM to make adjustments to the air/fuel mixture based on whether the O2 sensors are reading lean or rich.The rear(downstream)sensors should not fluctuate at the same rate as the front sensors.If they do,chances are you have a clogged CAT.
