Pretty sure they got turned off. I was constantly getting either the P2096 or P2098 code after installing L/T headers. I even installed some O2 extenders which did not help. Only after they were turned off was when I was CEL free.
Only pre cat O2s provide closed loop feedback. Post cats are only for monitoring performance of the catalytic converter. My aftermarket cats were efficient enough that I never had to disable post cats . Only when I completely eliminated the cats did I need to disable the post cat sensors

Good to know, thanks! If you don't mind sharing the STAR pathway or putting it in the sticky up top, that would be appreciated!
I was about to put this into the sticky. I was also going to recommend turning off EGR and secondary air injection pump while in there... but you have done all of that in the link provided
So It looks like I'm going to buy an generic extension and use posi-lock connectors since you can't solder them, hopefully works,since I haven't found a plug/play extension that first our 02 sensor connections.
as far as i know its a mercedes specific connector type. an idea i had when i was going to do this was find a mercedes model that has the same connector type but is a longer harness and just buy those O2 sensors. from my research a front left o2 sensor on a 164 chassis with a 113 engine has a sensor 10 inches longer than our rears. the pins are the same but the round connection housing is the black one (front) instead of the white one (rear). these connectors easily come off and you can insert the pins into the correct connector.

Thanks Rocman, very helpful, $210 - $253 each online, to cut, or not to cut...
That's for the genuine factory part. The Bosch oe part is much cheaper.
ah, yes, $98 on amazon, can't quite tell on their image how long the pigtail is, but I may just order one since amazon has a decent return policy if it doesn't work, thanks for you help!
