It is always best to rejet after an exhaust, they are set most times from the factory a tad lean for emissions and adding an exhaust will lean you out even more and this is bad for the motor! My advice would be to rejet and avoid any damage due to overly lean conditions. Just my 2 cents[img]i/expressions/face-icon-small-smile.gif[/img]

at least go a full turn richer on your mixture

a pipe swap should always have a airfilter and dyno kit, which includes a new needle

bang for the buck is nearly ALWAYS the airfilter+dynojet kit+inline fuel filter

If you change the head pipe you are changing the back-pressure too much to leave the stock jetting. If you were just doing a slip-on you can get away without jetting. But he head pipe is where the power really comes into play.
