Some people run without a cat, but if you're either 1) ecologically conscious, 2) in a state with emissions testing, or 3) have a 96-98 OBD-II car (if you need hookups for two O2 sensors you must), you should probably run with a cat. The second O2 sensor works as a baseline reading so if it isn't run behind a cat, you might get a check-engine light or suffer reduced performance.
Not sure about the flex pipe. I believe it allows for the normal movement of the engine without affecting the rest of the exhaust system.
