Wide band sensor location suggestions

I finally bought a wide band. I’ve noticed the 940 downpipes have a bung in front of the catalytic converter. Would this location be acceptable for the sensor?
 
WBO2 sensors need to be installed post-turbo but pre-cat, with a recommendation to be as far downstream as possible (close to the cat) to keep EGTs lower and therefore extend sensor life.

For reference, the mounting details on page 10 of the AEM UEGO instructions below apply to the Bosch LSU4.2 sensor which is a commonly used sensor across a lot of brands
 
Weld bung into exhaust header. Literally all it says.

This is the type of stuff that really pisses me off. It feels like they're selling products that they know nothing about, which is not what I'm paying for. At least give me best practice and why. Show me you know more about this than I do, not just that you have access to resell it.

Touched a nerve there.
 
The hard part is done. Ran out of time to do the wiring.
