Mine is in the I-pipe roughly at the trailing edge
of the passenger's door (so I can wedge the WB
cable and keep it off the pavement). You need
to be sure that the exhaust gas temp wherever
you put the WB never gets higher than the WBO2
heater setpoint or you will get inaccurate data
until the heater is back in charge. So as far back
in the collector as you can, if you must put it in
the header, but preferably after the merge since
you are working against a combined airflow,
combined fuel delivery model (so don't want to
favor one bank over the other).

I've heard that the driver side bank tends to be the leaner one and since you cant adjust each individually then if I take the A/F reading from this bank I should always have the safest reading.
