Yoshimura · RS-5 · Slip-On
The Yoshimura RS-5 Slip-On Exhaust / Carbon Muffler is a Street Series Exhaust System designed for the Honda CBR600RR 2009–2026. Built around Yoshimura’s race-inspired RS-5 silhouette, it delivers a distinctive trapezoidal look that matches modern sportbike styling and under-tail-inspired lines.
