If you're going to add a stinger to the end of the spooky pipe, I'd cut off the little angled nub flush with that flat back cap and grind it out large enough to fit a piece of tubing just under 1/2" in diameter. Cut the piece of tubing about 6" long and slide it into the ground out hole about 1/2", set the angle you want and then weld it. You can cut it down any length from there and even add a silencer to that if desired.

Nothing is out of my realm,
if it doesn't fit, make it fit! Beer is the answer....what was the question?
