Yeah, without an exhaust hole, you would have a problem. You need draft to get the intake air to fuel the fire. Did you have just the bung hole opened at least? Having the pipe wouldn't make a difference, as long as you had some sort of exhaust port.
With your 2" pipe in there, you should be fine. Try it again. You should be able to get to 300+ degrees with all three vents open and enough hot coals to start out.
