81 CAT DELETE

so ive been searching through some threads about smog system removal / cat delete etc etc. but i need advice specifically for the 81 . will i mess up the computer by removing the smog system and cat?  i see by the pump there are some electrically operated devices / solenoids that i assume operate with the computer.  just to be clear , the removal of this system and cat will just require capping off one fitting on each side exh manifold( the one going into the check valves)?  also , just unplugging those electrical connections and tying off someplace will be ok?  would it be best to leave the AIR system electronic valves plugged in so the computer still detects them?

option 2 is to just remove the belt and move on with my true dual system while just cutting the AIR pipe to the cat where it is.  does the 81 have an O2 sensor? and with it gone will it throw CEL's?
