The up pipe needs to be long enough to prevent smokeback, but still in enough heat to light off the smoke. About where you have it pictured is about right, maybe even a little shorter. We could get the upper barrel glowing when it was running full bore. That pipe needs to be supported somehow, the barrel ends are not strong enough to hold that much.

Option two is a 55 gal pocket rocket design.
I would want to get more heat transfer off of the exhaust if possible though, so I would be looking at trying to pipe it into a secondary barrel as well to increase the exposed surface area for heat transfer. I could possibly incorporate the barrel with the extra piping like was seen in the video for the double stack stove to get even more surface area.
