But you have forgotten all about the scavanging affect. Basically you want your exhaust gasses to move fast enought to create a vaccuum condition that is going to pull more gasses. To slow and you dont get that. This is really helpful in lower rpms where there is not as much flow. According to your theory, everyone should be running open downpipe. Have you ever driven a car with an open down pipe and then put an exhaust on there? A similar concept would be siphoning. Not the same thing, but similar principles. Void created needs to be filled, motion of water keeps creating a void that keeps needing to be filled. Motion of water is aided by gravity.
