If you can imagine it you can mod it, for the most part. The exhaust would just be one part of the puzzle though, If you're opening up the exhaust then you might as well open up the intake with some sort of aftermarket product or mod, and then jet and adjust carb accordingly. Anyone else want to chime in!?

Not sure how restrictive your stock muffler is compared to the 150's. My guess would be it will increase perfromance a bit, but usually adds more noise as well.

Jetting will most likely need to be addressed for sure.

Sorry, i have no experience with the 250, so I can't suggest any jetting.
