How do you Relocate O2 sensors On Exhaust

Okay i just Got Somee headers and a Downpipe for a Good price only Thing is , the headers are for a DC2 teg so the O2 sensors is on the headers instead of the downpipe like DA’s. How come i possible relocate the sensors to the headers
any suggestion would help alot

i would weld the o2 sensor whole u have now shut and buy a new “o2 bungs” and weld it into the proper spot. i wouldnt splice into the wiring b/c the o2 wire have a very small voltage signal and a solder could change the resistance going to the ECU.

my 2cents.
