if you don't understand what smog pumps do then heres how it works....
the smog pump is set up to inject air into the unburnt gases in the exaust, it then ignights and burns hotter when reaching the catylest. it then able to make the cat work more effectently by burning hotter. so with that said the air pump only promoates effecency in the cat, so if the cat is gone the pump does no good.
