Any evidence of this documented? I always here people say this, but logically it makes no sense. I mean an engine is an air pump. The less restriction the better. Now if there is some reversion in the pipes, or it ruins the scavenging effect I understand, otherwise I don't.
It's not true anywhere in physics so there must be something OTHER than back pressure reduction going on. NO engine NEEDS back pressure.

PS I'm not picking on you in particular. I'd just like to know what is happening really.
