Ok, Just got this bike earlier this week. Ive been reading, researching like a mad man. More hours than my wife thinks is necessary lol. So much info, I have myself confused. My M4 exhaust is supposed to arrive monday. Ive done header replacement on multiple bikes, but never on a bike that has exhaust valves and servos etc. I will do a flash with Dano in a few weeks when funds become available again. So..... in easy terms.... what do I need to do to change out the exhaust. Do i need to do this "servo buddy" thing? Thanks for the help, again ive been reading everything I can, Im trying to make sure Im prepared with everything I need come install time.
