Ox-senser location... does it matter where you pipe in the o2 sensors in the exhaust? i am using f-body manifolds and the drivers side is tapped for one sensor, but i am using a second on the pass side, but obviously its gonna be a little downstream from collector. (makein pipes from scratch, no y-pipe). any input on this?

The factory locates the pass sensor about 3" behind the end of the exhaust manifold on the top side of the pipe.
The closer to the motor that you can position the sensor the faster it will warm up to operating temp.
I have also heard that you should try to avoid putting the sensor in the bottom 1/3 of the exhaust pipe if it is in a horizontal section of pipe since most of the moisture will congregate toward the bottom of the pipe. So locating it above the moisture will help extend the sensors life
