The sensor should be mounted on the upper half of the exhaust tubing with an angle of more than 10 deg due to condensation in the exhaust tubing.
Other things that needs to be considered for narrow band sensors are:
It is important that the location is right also with regards to distance due to the temperature drop in the exhaust gass < 600 F. To far away and your sensor may react to slow also the further away you mount it the slower it will react. It may also interpret this as a lean condition and start adding fuel. This would also be worse at idle due to lower exhaust temperature. Switching to closed loop may also be a problem. So if you are unsure of managing keeping within the limits of the sensor I would go for wide band or program it in open loop. Remember the narrowband is only accurate at around 14.7 :1 the rest is useless . Better safe then .......
What management system and sensor are you planning on using ?
