Yoshimura RS-4S Full Stainless Steel Exhaust System for '12-'16 Kawasaki Ninja 650/ER-6n
The Ninja 650 is a unique and versatile machine. We took the opportunity to create a system that would not only improve performance, but also enhance characteristics inherit in the original engineering, i.e. centralized mass and low-center of gravity. We were able to achieve this through use of our RS-4 Muffler mated to a Full System, giving Ninja 650 owners the ultimate in Yoshimura power.
Yoshimura Full System includes stainless steel RS-4 muffler with turn-out carbon fiber end-cap, low-volume insert, stainless steel header and tail-pipe, installation hardware, and step-by-step instructions.
