Which one is it? I know there's 4 of them.

You are correct, there are (4) O2 sensors.

(2) before the catalytic converters.

(2) after the catalytic converters.

(1) where the two pipes come back together before they split again into the dual exhaust.

This last one is your main catalytic converter.

The last time I checked, 2+2+1 equals 5.
