The RS-5 is one of Yoshimura's most popular pipes, and for good reason. Its trapezoidal shape appeals to the eye and really captures the spirit of racing. It also complements the look of any sportbike, following the race-inspired lines of today's under-tail muffler configurations. The RS-5 features a straight baffle with a removable low-volume insert, and trick carbon fiber cone-shaped end cap. Trapezoid-shaped sleeve. Large volume of packing material. Straight baffle for ample flow. Carbon fiber end-cap. Stainless steel header and tail-pipe.
