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?

When you diverge from design parameters that much, you're on your own and it usually has mixed results.
Bad ones? :lol:
