Long Tube Headers: Where to put WB O2 sensor?

[DJHA90]

Ive got ceramic coated long tube headers. Should I install the O2 bung in the 1st part of the h-pipe, or go ahead and have it installed in the collector of the header?

Thanks

I have mine in my X-pipe between the collector and the cross-over. That was easier for me than putting it in the collector. Reads the same as the O2 sensor (when its working)

I have mine in the collector on each side.

I've seen some say their wb cautions about getting too close to the heat.

Might wanna do a bit of research
