Bank 1 will be the Driver's side of the engine. If it's a catalyst inefficiency it will be the rear o2 sensor causing this code. So look after the cat on the driver's side exhaust manifold. Are you sure that it is the sensor and not a bad cat? Did you test the cat first?

swap your rear o2 sensors and see if you get the same code on the passenger side (bank 2 sensor 2)... if you still have the same code on the driver side after you swapped the sensors then it's more than likely a bad cat
