Ed,

Ever think about a pulsating air pump.  Build it like a drum with one-way reed valves.  Sound waves beat the drum and pumps air to the intake, and if timed right would offset wave pattern in the intake.  Just a thought!

AND give up 15HP?  Nope, besides need some motivation to do some more muffler design work (play).

I keep thinking about all the power in that exhaust pulse and the potential of doing something? with it {:>)
