ALL lt1 guys running duals. I have a question for anyone running duals specificly with OBDI and 1 o2 sensor. I got a buddy that will do my exhaust im running stock manifold right now till im shut the car down in the winter for mods so im gonna cut the stock Y and build off that and just delete the cat. My question is can i leave the o2 in the stock place on the pass side or do i have to relocate it. if I do have to relocate it what can i get to do this with.

Your car has O2 sensors on both sides. OBD II cars… '95 California cars and all ‘96 and up cars) have post cat sensors that check for catalytic converter efficiency.

i agree....untill you ditch the manifolds, duals aren't gonna show you any gains. once you've got long tube headers, then have the exhuast made to fit those, and the headers will have bungs to put the o2 sensors in.
