I run a pretty short pipe too Wicked,(yeah, it's loud.) but ya gotta leave a little something in for some back pressure. I cut a used stock pipe all the way just before the honeycomb inner baffle. Used because the honeycomb always clogs a little producing the back pressure you need. Otherwise there's nothing to prevent fuel from simply being pushed straight through, leaving less in the cylinder to burn. So what yer doin is using(wasting) more fuel for less POP. 2 strokes need just a little back pressure. You can see in the pic how short mine is.
Sorry, To be more precise, NON REED VALVE 2 strokes need back pressure from the exhaust.
