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

The Yoshimura RS-4 Slip-On exhaust has been put to the test and has proven its capabilities at the highest level of competition. In 2010 the RS-4 muffler helped Ryan Dungey claim the AMA 450 Supercross and Motocross championships in his rookie season. The Yoshimura-backed GEICO Honda team also took home both East and West Coast Supercross Lites titles in 2012 using the Yoshimura RS-4 exhaust.

Utilizing the same R&D that helped bring success at the national level has resulted in a unique exhaust design that provides an unrivaled combination of power and quiet exhaust note. The Yoshimura RS-4 Pipe features an innovative carbon cone end cap, a two staged stepped baffle, and a polyresonant duplex chamber which acts as a muffler within a muffler to help save weight and centralize mass.

Features:

• Pentagonal-shaped sleeve
• Polyresonant front muffler chamber which helps reduce noise
• Two-stage stepped baffle
• Yoshimura Race Series muffler
• Carbon fiber end-cap
• USFS Approved spark arrestor available separately 
• 100% Made in the USA
