Well, it seems that Mike Jez (don't take this the wrong way) often
experiences uncommon results to common problems.  IIRC, the JDM header
has the O2 sensor pretty high, effectively mimmicking the USM exhaust
manifold's O2 sensor location.

Again, I'm going to bet that it's the one topside, since the function
(taking another big bite of my banana) of the post-cat O2 sensor is
mostly to make sure that the cat is functional.  The one on the manifold
is the one that checks mixture and tells the ECU to enrich or trim the
fuel supply, thus affecting your mileage.
