I am picking up my new pipes on Friday and can't hardly wait. I have ridden it stock for 4000 miles now and am ready to start turning heads. I can't afford to buy the Power Commander yet, probably get one in the next month or so. I am wondering what to expect with running the new pipes without the new fuel mapper. I plan to marble the reed valve to cut down on the popping on decel. Will I notice any other bad side effects after installing the new pipes?
