Yoshimura RS-4 Stainless Full Exhaust

Yoshimura RS-4 Stainless Full Exhaust

The work that went into developing the RS-4 muffler has paid big dividends in Off-road Racing; winning multiple Supercross and Motocross titles since it's inception. We've developed the current generation RS-4 based on that research & development, and the result is a unique design that provides an unrivaled combination of power and quiet exhaust tone. The RS-4 features a Polyresonant duplex chamber and two-staged stepped baffle for increased performance, while a carbon cone end cap finishes off its innovative styling.

Features:

• Pentagonal-shaped sleeve
• Front muffler cap functions as a polyresonant chamber which helps reduce noise
• Two-stage stepped baffle
• Carbon fiber end-cap
• Stainless steel header and tail-pipe
• Repack Kits, optional Inserts and Spark Arresters are available for all models
