A: Yes. Normally any time you are switching from the stock exhaust to an aftermarket full exhaust system it is recommended that you retune the fuel mapping on your bike as the aftermarket exhaust is going to have more exhaust flow out, you will more than likely need a different fuel/air mixture going into the bike's engine.
