usually, remapping is not necessary on our bike if you only change the exhaust. i ran mine for over a year with an exhaust change with much the same setup as yours. if you change the airbox that is a different story. you would then need to put a power commander or cobra fuel processor on it. now, don't misconstrue what i am saying. it can't hurt anything to go ahead and put a processor on, it's just not necessary.
