Yes, please do clarify a bit.

Caterpillar typically uses a distinct style fo stack on their heavy machinery, especially the large dozers, excavators, and mining equipment. It's usually a piece of straight pipe that is cut and wedged so that it angles at about 45* for a few inches...usually the bottom length is about half the diameter of the pipe. I've seen "small" 4" dia all the way up to 12" dia sewer pipe. There's a guy on DTR that has an 8" or 10" stack that he's going to install. Looks like he took a culvert and put it in his bed.

If you go to Cat's website and look around at large equipment you will see their stacks.

Oh, kinda like a bullhauler turnout, but cut, instead of bent?

Sort of. They are definitely cut to make the turn but the turned extension is usually very short, just barely enough to get the smoke to travel in a slightly angled direction.
