Guys, I have a few questions.... I own '09 Nightster and have just ridden it for about 200 miles... The question is can I install V&H Shortshot on such a low milage bike???? Also, can I install the exhaust without any other modification??? Will the engine be OK??? What effect does just installing exhaust do to the bike and how it rides??? I heard from somebody that installing shortshot on otherwise standard bike will hamper the performance from middle to top end range of rpm. Is that true??? Or should I go the route of exhaust+air filter+some type of ecu tuning at once????
