best way to remove cats?

This may not matter in your state, but if Illinois does require state inspections, wouldn't the CEL trigger prevent you from passing any inspections? Here in NY/NJ, if you have a CEL light, and then try to mask it by disconnecting your battery and resetting the light, you still won't pass the inspection because your readiness codes will not have reset until you drive a certain amount of drive cycles, and by then, your CEL would reappear. Just curious.
