yes

The primary O2 sensor is the one used for A/F readings. It is located before the catalytic converter (on the stock manifold/cat), so a race header won't affect its accuracy.

cool, I was wondering the same thing, because I heard with a test pipe you can run lean. However, that may just be with the reflash and test pipe. Can't recall, I did all my research just by searching before the crash.

Is a standard a/f gauge more accurate on our cars due to us having a wideband o2 compared to older model hondas?
