RPM activated exhaust cutouts?

Perhaps I could design an rpm/load dependent "exhaust diverter system" as opposed to an "exhaust cutout system". That way, the exhaust will ALWAYS go through at least one muffler. That should also take care of the leaking problem.
So if what you say is true regarding our NA engine always needing "some" backpressure, we can have at least switch between "some" to "more" backpressure.
I'd think you'd agree that at low rpms the optimum backpressure would be different than the backpressure that is optimum for high rpms. Such a diverter system could allow for such an optimization.
I want to keep this project below $1500 or else I'd rather just put that money towards an HD Projector and a 120" screen for my home theater.

the power gains, especially for $1500 (
) will be miniscule (if any) with the "diverter system" compared to a full cat-back exhaust using 2.25in. tubing, an X-pipe and high-flowing mufflers.
