i recently added a two bros slip on and along with my gutted header cat and airbox mod it pops badly i know you can do the ais block off to help but what does it affect doing it i mean why is it on the bike if you can just block it off??? also im getting a pc and dyno tune so is the ais block off neccassary or will the pc and dyno fix the popping.....p.s. the bikes shoots flames out ALOT now
