will my speedfight 2 100cc go faster if i add new parts?

hi there
i have a pm tuneing 360 exhaust on already with everything else standard on my bike and if i get a mollosi 21mm carb and a mollosi variator and a clutch race will it make a big differance? thanks and just by haveing my mp tuneing exhaust on with standard parts will this make my bike go slower because its a tuneing part and my other parts are just standard?
