Notice I'm not getting into a lot of things like valve timing/overlap. The simple point to understand is that a properly designed exhaust actually helps evacuate spent exhaust fumes from the cylinder to prepare for the next boom-boom. If you want to take it to that level then I suppose we could.

I'm pretty sure you've heard of variable intake runners for low rpm and high rpm intake air management. We're pretty much discussing the same fluid dynamic concepts, just for exhaust rather than intake.

Please do some research before responding though. You might actually be influencing some people into believing you.
