Those with stock O2s in downpipe...

What did you do with your O2 wire harness? Did you shorten it or just coil it up and tuck it somewhere?

PO of my car cut the wires from the O2 sensors, and soldered on the O2 wire extension harness connectors so that there is just a short lead from the downpipe over to the main harness at the fender. But I need to replace the O2s and don't really want to cut any of the wires as I've heard 02 readings are very finicky from the ECU's standpoint and any wire butchering can alter the signal.
