Cutouts for Strip only, beneficial?

IMO, the only way cutouts might "add" something when open is if they open the uncapped side while CLOSING the exhaust side off. None do that "that I know of". ......and I haven't looked for any that do, because it's never interested me. But all the ones I've seen basically leave the exhaust side open when they open the uncapped side. This allows the exhaust to go both directions and it seems to me that wouldn't be beneficial to good flow. Now If you could make a dedicated long "collector" on the uncapped side, and somehow fix it so is sealed off the exhaust side while opening the uncapped side, AND that transition was good and smooth then you might be into something.

Been thinkin on that issue myself Rusty. A guy COULD buy 2 sets and rig it up so 1 set closes and the other opens. A little cutting and welding ............not that hard. BUT, the cut outs in the exhaust side would be restrictive when the loud side is opened up. OR.......

Some genius needs to invent a sort of "U" pipe that bolts to the headers, with a blade that just goes back and forth, from the open side to the exhaust side. Doesn't really sound that difficult to engineer if you're already making electric cutouts.
