Any time you increase or decrease the air flowing thru the engine enough it will affect the performance. Typically people will add a 4-1 pipe or pod filters that requires them to rejet to a larger main and pilot jet. I don't know enough about your particular bike to answer your "pressurized" question though. Hopefully someone has first hand knowledge of your setup and what a good starting point would be for rejet. Either way, if you are going to stay with the pipe and filters you will need to know what jets you have installed.
