The difference from the pipe and airbox mods was like going from a strong 125 2stroke to a 250 2 stroke.
Make sure you open up the airbox so she breathes better on both ends to get the full effect.
Oh yeah depending on your elevation and temps youll have to richen every circuit.
The pipe and air box made way more difference than the cam did. And the next best mod for power accelleration and response would be a 52 tooth rear sproket.
