ok someone square me away with this issue. How important is it to have a good working exhaust. My baffles are rotted out and are crazy loud. I'm assuming it has zero back pressure because of this. Secondly how or what does back pressure do to a running motor?

As Jayel indicated, usually some sort of baffling is required, or you'll have to invest a lot of time in re-jetting and tweaking, and it still may never run right.
When you diverge from design parameters that much, you're on your own and it usually has mixed results.
