OK read this and open the picture below. so you know exactly what I am talking about. My friend has a 250ex (wait dont run off yet it aint about a 250ex) but neways he bought a DG exhaust it runs well ok I guess here is where my question comes in. ok the part of the pipe the long piece ======== that enters the pipe itself is in a strait line. I wondered if that is why some pipes are different and what one is better such as the Graydon. The part that goes in it is big like a cone I figured that would be more horse power kinda like the yoshi pipes are made.(look at picture i cant explain).. well thankz please explain.....

i think that would be the reverse megaphone, if im right it creatse some kinda or a sucktion so the pipe can be really free flowing for top end and still have the back pressure for low end riding. someone correct me if im wrong
