Most wideband instructions tell you specifically not to recal with the sensor in the exhaust stream, even if the engine has not run in the last 24 hours as there is the posiblity of exhaust eliments in the air in the pipe that can distort the calibrationa and why calibrating it in free open air is best. Some guys have said you could put a shop vac on the tailpipe and open the throttle body up to allow fresh air to pull through for a while and then try it but still isnt suggested for the most accurate read.
