OK just for a visual reference of how you make this, I took some pics:

And yes, that's a 2" rubber cap with a valve stem installed in the end (drill a hole, screw down the locknut on the stem). You cram it into the end of the pipe and as you inflate it, it can only force the seal to be better. Using this rig, my roommate's 04STi held pressure for several minutes.
