Description

Small displacement dual sports, like the Honda CRF300L, are an absolute blast to ride, and adding a little bit of extra power to the low end of the power delivery only adds to the fun, not to mention the added style and sound. Yoshimura's RS-4 Full System Exhaust gives 14.2% max HP to the low-end while retaining equal amounts of top-end power compared to the stock setup, all while dropping 2.4lbs of weight from your CRF. The Yoshimura RS-4 provides an unmistakable sound and eye-catching style with a stainless muffler and gloss carbon fiber end cap.

RACE EXHAUST: This exhaust system is for closed-course competition only and is not intended for public roads or land.
