I have an 02 1000 and I am considering the devil shotgun exhaust. the kit does away with the exhaust valve. does anyone have an idea what my actual torque loss will be? i know the valve was designed to make the bike more rideable at lower rpms, which is mainly the riding i do. removing the valve will undoubtedly move the powerband up in the rpms, but im not sure by how much. if anyone has had experience with similar systems or just know what the effects will be, your input would be greatly appreciated.
