RS-4 STAINLESS/ALUMINUM FULL SYSTEM:

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.

 

RS-4 STAINLESS/ALUMINIUM SLIP-ON: The RMX450Z off-road bike is bred from the race winning RM-Z450, but the RMX450Z is a fuel-injected torque monster built to perform on the trails. Add a Yoshimura exhaust into the mix and you've got yourself an unbeatable trail machine. The RS-4 muffler is a unique design with predicated power, a side benefit of a quiet earthy exhaust note that speaks volumes for performance. It was an obvious choice for the RMX450Z.

Slip-On comes with a stainless steel tail-pipe, aluminum muffler sleeve, installation hardware, and detailed step-by-step instructions.

Stainless Systems come with an AMA-approved sound insert.
