Yoshimura Titanium Carbon Fiber RS4d Exhaust System. Used less then 1hr on test bike, looks and performs like new. The RS-4D boasts a unique dual-outlet design that increases the amount of open area at the exhaust outlet. With dual internal baffles, the RS-4D increases the exhaust gas flow rate, resulting in smoother power delivery and increased throttle control. It also offers increased horsepower and torque throughout the power curve, especially in the bottom- to mid-RPM range where riders need it most. Includes springs, use your stock bolts and nuts for mounting.
