Not one internal ombustion engine on the planet needs any type of back pressure. Back pressure is bad! velocity is good. You want an exhaust system that keeps velocity up. in the early days of tuning back pressure was confused with velocity and hense the parroted incorrect "knowlege" continues...

Two strokes are ESPECIALLY senstive to backpressure. They really really really do not like it.
It is critical to not confuse resonance tuning with backpressure. Resonance tuning *is* important for "closing the door" port wise but it couldn't work at all in the first place if there was backpressure in the system.
