If you buy the pro-flow kit and remove the airbox lid, yes. No, you must rejet.

If you put in a new drop in filter, leave the airbox intact, and throw a slip on with spark arrestor and quiet core on then you'll see little or no increase in performance, and you won't need to rejet but it'll stumble on decelleration and top end.
