Pressure obviously plays a role but it is not the primary concern. Maximizing the benefits of the exhaust pulses and the effect on scavenging are most important.

Right. We are talking about a system that operates at many frequencies and flow levels... not just one. It stands to reason that it will be difficult if not impossible to optimize a non-adjustable exhaust system for whole spectrum of operation. What we have now is just a rather crude compromise that delivers acceptable but not optimal results across the whole range.
