O2 Sensor Location Help

[97GTzbban1]

P0141 code is coming up so I would like to know where this O2 sensor is located so I can change it myself. It says "bank 1, sensor 2". I've looked around and can't seem to find the exact location....thanks!

one sensor is on top of the rear exaust manifold then other is on the exaust pipe by the catalytic converter

sensor 1 would be on the rear exaust manifold, and sensor 2 would be after the cat
