It could be installed in baffle cone to change tuned length and cone angle or maybe right next to port to increase back pressure at lower Rpms
Just thinking of mechanical pipe shape changers because now only dealing with one pipe, it opens up possibilities...
Although I'm really considering doing the trombone bellies on my 400 project using the skinny pipes in delta formation... Gotta dream right? ;D

55 stay alive... Lol
I'm easily distracted, constantly day dreaming and very stubborn... So says my teachers, parents, wife, kids and people I work with... But what the hell do they know. ;D

See I was thinking each header could have a low strength valve at the junction to the chamber. One that would open to expel exhaust and snap shut again to maintain good compression - a poor boy's power valve..could be rubber, or like a steel reed...

I just did a quick check... I'd need to shorten the pipe 3 inches to raise the rpm 1k... Seems allot for a little! Maybe not worth the effort?

Or maybe valves in the head, and remove every other power stroke......

C'mon John, we might have to admit that we've been working on exhaust reeds, which were my idea!

Reed valves in the exhaust and moveable pipes are all possible I guess, but why not work convert the barrels to "power valves"?
A little welding and machining and you would be good to go.
Use electronic controls and use the PV not just to stretch the powerband, but to change pipe event timing to moderate some of the adverse wave arrivals.
I'm not sure if it would be possible to shut a valve on the other two cylinders every revolution, but it could be an interesting project.

How is the pipe joint to the header, looks like a slide fit as per a sled, with springs and a bull ring gasket? That would be cool!
