All Street Series systems are slip-on/bolt-on applications that do not require tampering with the vehicle's emissions control system, yet still deliver that special Yoshimura spirit in street-legal options for almost everything on two wheels. Yoshimura RS-9 mufflers from their Street Series, are specially designed to deliver added power and style to the Papio SS minibike. Fitting perfectly under the tail section of the little machine, the RS-9 slip-ons increase maximum horsepower and torque of the 126cc engine by 4 percent. On the street you can really feel the difference and the sound note from the RS-9 is nothing short of legendary. Plus, ditching the stock muffler will save you almost 2 lbs., as well as making the Papio SS even more fun!
