Your best option is to get a bung for the wideband sensor welded as far down the downpipe as you can. You can run it where the o2 sensor is but you'll burn through those sensors quickly.

18-36" from the turbo is what most say I believe. It should have came with a new bung to weld in. Bottom of the down pipe off to the side but on an angle so moisture doesn't sit in it.
