Anyone run one on a smaller engine like mine or know if they would work well or not?
You aren't going to hurt the torque curve. Pipes need to be sized proportionally to the expected flow, but a muffler servers a different purpose and works differently. For a muffler generally there is no such thing as too big, You'd probably want to just use the upper inlet and cap off the lower one
