I don't understand what you're asking. Why would you need to get a second o2 bung installed in the header? How many o2 sensors does your car have? I'm assuming just one since it's a first gen B16 in a 91 chassis.
Do OBD0 motors have 2 sensors in the exhaust manifold?

is the first O2 sensor on the front of the manifold?
That's wierd...I never knew OBD0 setups had two sensors in the manifold. I figured they'd have just one. In that case then I'd look into a header for 90-91 Integra like eg6sir said.
i just spliced my 2 o2 sensors together. runs fine. do yourself a favor and get a 2 piece header, mines a 1 piece dc sports and it was an absolut bitch to put in.
