As the official exhaust of the Yoshimura Suzuki Supercross/Motocross team, this exhaust was designed with one thing in mind, winning races. The RS-4 is a unique design with predicated power, a side benefit of a quiet earthy exhaust note that speaks volumes for performance.

The work that went into developing the RS-4 muffler design paid big dividends in 2010 with Ryan Dungey winning the AMA 450 Supercross and Motocross Championship series as a rookie in the same year, and again in 2012 with the Yoshimura-backed GEICO Honda team winning 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.

This Full System comes with a Stainless steel header and mid-pipe, aluminum muffler sleeve, installation hardware, and step-by-step instructions.

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