The air pump on a Series 4 car (1986-88) is used to pump air to the catalytic converters to keep them cool and clean. You need to simply remove the air pump, unless you have the stock cats. If you remove the pump, you can destroy your cats!!!!!!!!!! If you remove the cat, gut it, or put in a racepipe, you will need to wire open the auxillary intake ports, as they are backpressure activated, and will no longer open, destroying your top end power. Hope this helps!!

If you get rid of the airpump, you might as well by a block-off plate and remove the ACV.
