Air Pump Question

91 S5 stock w/corksport catback:

Recently, I popped another alternator belt, so since I had given it the proper amount of tension, I figured I should check the pulley, and I found some pretty rough spots on the alt. pulley.

I decided to replace the pulley, and the most cost effective method was a dual alt pulley kit from Banzai.

Anyways, my real question was, I need to swap to emissions legal very quickly, so the air pump is staying in place, but iirc the air pump helps with the variable intake ducting. Should I use only the one part of the new pully and keep the air pump cycling, or should I just remove that belt and double alternator pulley they car?

This is my daily driver, and I don't want any streetability to change.
