I have a like new YFZ header and muffler lying around. I was kicking around the idea of trying to fit it to an YTM or maybe my Pro-Hauler. The Pro-Hauler has a 230 Power plant which is not far off from the YTM’s I have. Would a factory exhaust designed for a 450 four stroke benefit a 200, 225, or 230 four stroker? I almost see it hurting more than helping. Any input on this?
