Thank you Konrad.

I also disagree that peak RPM is the "holy grail" of a tuned pipe. It's been shown that you can over speed the engine and loose power on a given pipe. The piston closes the exhaust port before the rebounding sound wave can push the escaping fuel charge back into the combustion chamber.

We all know that RPM's is power. But too many RPM's on a given pipe volume can actually hurt performance.

I'm calling Macs tomorrow and ask him about his theory in designing the aero tuned pipe. Was it designed for all out RPM? Or was it designed for a more mild boost across a flatter curve?
