Where is the optimum location for the O2 sensors? My car is stock minus the cats and I have 94 manifolds that I am using. The car is a 93 and the drivers side O2 was in the manifold originally and on the down tube before the cat on the pass. side. These were the stock location as the car was bone stock as I got it. I bought a set of 94 manifolds here and the pass side appears to have had the O2 sens. in the manifold in 94. Just didn't know if one location was better than another. Car will remain mostly stock save for no cats, 10% pulley and MK VIII MAF no other mods except Cobra brakes.

Doh! Make that a 5% pulley not the 10%.
