The best position for a wideband sensor is in the header collector. Post cat exhaust is leaner than the gases in the header/collector. How much leaner depends on a lot of things. I know some guys will temporarily clip an afr sensor in the end of the tailpipe for reads while tuning. I don't have any direct experience with this technique by you may want to just try it and see how your reads look. If they look off, then I would install it precat if possible.
