    Exhaust Back Pressure

    My latest machine (82 200) starts, idles, but when you throttle up, it runs rough. The most obvious thing is the loud aftermarket exhaust system. It didn't have a baffle in it and it was leaking where the header joins muffler. Think this could be it?

    As always....Any advice would be great!
