02 bung placement with RPW race

I know the RPW racing headers will remove one of my cats, and I'm buying a high flow cat. does the o2 bung go on the engine side, or the exhaust side? or are there two? Thanks in advance

engine side. if you want to avoid cel, exhaust side my be your way to go but the wires will need to be extended.

As you know, we've got 2 sensors. 1 sensors has a dedicated bung in the exhaust manifold(Sensor 1), and the other one connect right before the 2nd cat(Oem) or after 2nd cat(avoid cel but extend wires)

I have the RPW header. I had them weld a bung onto the right-most pipe (when looking at it installed in the engine) about two inches after the bend. No CEL issues at all.
