The instructions with your wideband will tell you how far away from the block the sensor should be. I think my AEM was 18-24 inches from the block, so mine sits about 3-4 inches from the current bung for the 2nd o2 sensor

it wont matter...go with about 4 inches from the current bung like everyone has said so far and your good. Do it about an inch after the curve away from the original bung on the s pipe where its at its most straight point so you dont get turbulent readings.

+1 Which would be the downpipe, instead of the S-pipe.

Thought I would do a google search on where to place a wideband sensor and came across one site that said:

On turbocharged engines the UEGO sensor must be installed after the turbo charger, if not, the pressure differential will greatly effect the accuracy of the unit. In applications with a catalytic converter, the UEGO sensor must be mounted BEFORE the converter. In applications with an auxiliary air pump, the UEGO sensor must be mounted BEFORE the pump input to the exhaust stream. Installation angle should be inclined at least 10° towards horizontal (electrical connection upwards, see diagram) which prevents the collection of liquids between sensor housing and sensor element during the cold start phase.
