Not sure since the 94 is OBDI. I got the extra O2 sensor flange from Slee and had Murphy's in Warrenton do the exhaust from behind the y pipe. If all you need is the 1 O2 sensor before the cat then you should e fine. I put on the y pipe myself then drove from Fairfax to Warrenton with straight pipes.
Nice! Yeah, I have 2 O2 sensors, so I dont know if that would work (the 1994 has the Y pipe after the cats). I might have to try to move them where the old PAIR system was or (as PDoyle suggested) just get some OEM stuff.
