Remove the heat shield just right of the oil dip stick with a 10 mm socket. The CAT should come to view. The top is sensor 1 and bottom is sensor 2. You will need a 7/8" oxygen sensor socket. Use NGK or Bosch oxygen sensor.

I would say use NTK (NGK's brand of Oxygen sensor), genuine Nissan or Denso. I've had some issues with Bosch sensors in Toyotas and Nissans. Soak down the shield bolts as the tend to rust and break when you try to remove them.
