<VV> angled exhaust tubes

I have seen angle exhaust on aircraft applications. I know they turn those engines slow at least the engines without the gear reduction. Looking at the stock flow numbers on American Flat Six I can see why you might still want better flow.

I don't know directly, but I do know that I don't see them on engines that are built to stay below 6000 RPM.  I'd guess, based on other data (like cams, air filter, etc.), that they don't really buy much below 4000.
