alright, seems like something that would get asked a lot, but nothing comes up in the search. What are you guys with dual cat cars doing for AIR fitments with single cat headers(like the MACS) are you just running !AIR? some kind of adapter

I bolted on some SLPs and for the AIR fittings i got a couple brass pipe caps. If you don't know already, you will need an S-pipe to connect the Y-pipe to your catback.

The headers come with the ports for AIR, so you can just keep the AIR and EGR on the car. I think we need an adaptor though because the thread size is a little different on the '94-'95 fittings. I've seen that some have just been able to use brass thread adaptors that you get at the hardware store. Otherwise you just buy the '94-'95 AIR fittings and put them on your car in replace of the ones you have.

Also, you will need rear O2 simulators or have them programmed out(what I'm doing)
