"Won't the entire system be limited as to air flow by the 4" corrugated flex hose?"

Not necessarily. When the flow of a fluid (a gas or a liquid) passes through a restriction, the pressure drops and the flow increases to allow the volume of the fluid to pass through the restriction. It's called the "venturi "effect"(http://sciphile.org/lessons/bernoullis-principle-and-venturi-tube). It's what makes an airplane wing lift an airplane and it turns compressed air flow into a vacuum. Corrugated flex hose is a different issue, and the corrugations do, indeed, limit the air flow in a DC system, bit the limitation is due to the corrugations, not the decreased diameter of the hose.
