A pic is attached of the stock headers with horrible merge collector and integrated cat converter.

You can see the 4 O2 bungs (2 precat, 2 postcat) I have referenced. The problem is extending the wires of the 2 precat O2 sensors so that they are now 4 postcat O2 sensors in order to not have CEL's when you install new headers that remove this terrible OEM design. I want to check with my local Pcar Dealer to ask his thoughts. I want to keep all O2 sensors if possible.

Maybe some other guys have done this successfully already?
