Well not sure what the inspection requirements are in your state. As far as the computer is concerned, as long as there are no DTCs you should be fine there. It should also pass a sniffer no problem if you have functioning cats and a visual will not be a problem almost 100% of the time even if stuff is removed (beside the cats).
