Its easy to get good low speed response and thrust with a low ported cylinder even with the stock pipe. Your nozzle will need to be bored and RPM set at 6700 or higher. A wet pipe will add 200-300 rpm and 3-4 MPH. The higher you raise the exhaust port the better the pipe works but response starts suffering a lot without high compression and a programable ignition. From there you have to get a bigger engine and pump.
