BADASSS!!!! I think you might have advanced the science here!
How did you join the connecting pipe? Is that where the JB weld is?
I've been lookin for barrels to start a new project, maybe like this. I have 3 racks and a diffuser plate but bending over into the smoke sucks and its blown back on me a time or two.
I'm thinkin a stove pipe damper between barrels would give a lot more control and divert smoke while loading
+1 on lower intakes too but it probly won't matter much.
