The rear 02 sensor is useless. It has nothing to do with engine managment. So no worried there. There is still enough exhaust moving through for it to get a reading and not trigger a check engine light with the anti-fouler mod. As far as wideband sensor, it needs to be placed before the cutout to log with the cutout open. Hope this helps.
