Are these Quincy pipes?

I'm not sure what you are calling "Staged Megaphones", but if you are referring to the bell shaped megs, the answer is yes.

Well, I just made up a term that I thought might be descriptive enough, Gene, but it wasn't very good after all. I meant an ordinary piece of exhaust tubing formed into an elbow AND a short straight section, with a cone-shaped megaphone welded to that. In other words, where with the old Quincy deflector pipes the megaphone cone began as soon as the elbow had turned 90degrees (so maybe, what, 6" from the piston), to make deflector pipes that looked more like looper pipes, the megaphone might start yet another 6" along (these dims are merely SWAGs).

But I think your answer is yes, so, how did they work (compared to the old style pipes) and were they individual pipes per cylinder or 2-into-1? Remember any power figures? When was this done? I never saw any out here, or maybe I just wasn't paying attention.

We experimented with various lengths of straight pipe between the elbow and the megaphone, but without much success.
