header question.
on the high port SR20's 91-93.5 there is a valve call PAIR, what it does is, inject air in to the exhaust so the catalyst converter can work better to meet EPA’s standard. so on the header there is a hole for that pipe to go through. but later model(94-up) . because the low port help reduce emission.. they have no need for the PAIR system any more
I happen to have a high port SR. any one who have performance header with that hole.. I was hoping to retain that system after I upgrade my header.. any one??
the hot shot header in the sticky notes.. don't have that hole.

The SSAutochrome header has an upper O2 bung, a EGR bung, an AIV bung, and an rear O2 bung. It is set-up for every year SR20 from '91 up to '02.

topspeed header (found on ebay) also has a AIV hole. however, it does not have a rear 02sensor, but sine 91-93.5 doesn't have a rear o2 it'll work on a highport

the SSAuto chrome is a very good header for the price. many members use them, and most of the guys on the sr20 forum use them
