1) Fabricate the stock US spec section 1 with the addition of bungs for CO2 sensors and EGT sensor (total of 3 sensors) for downstream.
*Question: If I were to use stock wiring by unlooming/loosening the cables to reach the back, do I still need to extend the wires and create new adapters?
2) Leave the EGT sensor and the 2 post-cat CO2 sensors unplugged. And get a tune to deal with the error codes.

bump for an answer!
also i would like to see the fabricated wiring harness for running the wires and holding them in place. i cant seem to find any pictures of how bmw ran the o2 sensor wiring on csl/euro cars.
