Ok, it's done!
I called my friend, and we went to an exhaust shop, got some free tubing, and grabbed his welder and a chop saw, then it took TWO tries to get the extension perfect! Zach tacked the piece in place, and then welded it using two jackstands as a support. Truck jackstands work really well for exhaust btw!

That's all, folks!
