Up front in the downpipe. More and more places are going to this method because it gets a more accurate reading, than a sniffer in the rear.
Any wideband instructions I've read always say to put your sensor about 12 to 18 away from the turbo or head. A long tube header and you want it in the collector or just after.
If I were you I'd put an O2 Boss in the downpipe and relocate your wideband sensor, then use it for the MS.
