Bank 1 is on the side of cylinder number 1 (drivers side)

Sensor 1 is before the cat

With longtubes the first O2 sensor, as already stated should be before the catalytic converter so a popular place to put them is into the collectors. Look there first or right where the Y-pipe joins the header on the drivers side.

Collectors where the primary tubes from the header merges.
