Test pipe vs full catback

You are replacing the catalytic converter with a straight piece of pipe (thus, test pipe). It has little to do with a cat back system. You can have a test pipe or no test pipe (retain the cat) with a cat back system. The only trouble is that you need to find an electronic device to fool the ECU since the O2 sensor will not be reading anything or it will be reading the wrong thing if plugged into the test pipe. It you don't, you'll get a CEL.

You don't need to buy an O2 sensor. The cat already has one. It's what to do with the one that was plugged into the cat. I don't know exactly how much the electronic device that fools the ECU costs (50 bucks maybe?) but again, you will turn something up with a search.
On the same note, only a few cat back exhausts will show some measureable gains and most of these are singles and are generally very loud.
