Yoshimura RS-4 Signature Series CARB Compliant Slip-On Exhaust System - Details
The work that went into developing the RS-4 muffler design paid big dividends in 2010 with winning the AMA 450 Supercross and Motocross Championship series, and again in 2012 with both 250 Supercross Lites titles. That same R&D has been directed to developing the current generation RS-4, a unique design that provides an unrivaled combination of power and a quiet exhaust note. The RS-4 features a polyresonant duplex chamber, a two staged stepped baffle and an innovative carbon cone end cap.
