? for those with '95 Macs on a '96-97

Could you desribe the pipe that was needed to connect the mac ypipe to the 96 intermediate pipe? Will a regular flange work to connect the intermediate to the ypipe?

I have to go out of town to get my exhaust done so I want to tell the guys what I need done over the phone first.

I have a set of 95 style Macs and ypipe. There is no cat or offroad pipe, just the headers and ypipe. Also have a borla catback but I don't think that should make a difference anyways.

I had 94-95 headers on my 97z, you'll be an s-pipe to connect the headers to the i-pipe. You'll also need different air fittings.

I figured I would ditch the AIR since there is no point in having it anymore (no cats), plus I already had the fittings welded shut.

Does the s-pipe bend enough to warrant getting a mandrel bent piece or is it just a slight bend?

Also what kind of flange will I need at the end of the intermediate pipe to hook up to the ypipe? Is it mac specific or just a standard 3"?
