A sport bike system without sacrifice. Power, torque and great sound. Our unique oval design allows the increased area for a triple-chambered baffling system that cancels noise waves yet permits high-velocity power pulses. The oval design also offers increased cornering clearance for a high volume exhaust system. And, each SS2-R is designed specifically for each motorcycle model. No "one-size-fits-all" mentality. One-of-a-kind styling, unmatched fit and finish, arm-stretching power... Vance & Hines signature billet-machined aluminum end cap finished off the look. GSXR1100 (F) 89-92
