Yoshimura CRF300L/Rally RS-4 Stainless Slip-On Exhaust

Honda CRF300L/Rally RS-4 Stainless Slip-On Exhaust with Stainless Muffler by Yoshimura USA.

Introducing the RS-4 for 2021 Honda CRF300L and Rally dual-sport motorcycles.

One of the fastest growing segments of the motorcycle market is the Dual Sport segment and we love the smaller bore dual sport bikes as they are an entry level to get more riders into the sport.

We stepped up to the plate and developed our RS-4 Slip-on for the all-new Honda CRF300L and Rally edition, the results were fantastic! Our slip-on provides 14.2% more max power on the bottom end of the spectrum paired with equal top end power as the stock unit.

The sound of the RS-4 is unmistakable, on idle and under load the exhaust note is music to ones ears.

• Pentagonal-shaped sleeve
• Front muffler cap functions as a polyresonant chamber which helps reduce noise

• RS-4 Stainless Slip-on weight 7.6lbs vs Stock muffler weight 10.0lbs.

RS-4 slip on exhaust includes an RS-4 muffler, USFS approved spark arrestor, all installation hardware, and step by step instructions.
