Slip on mufflers in applications whereby the catalyst is not contained in the original muffler is an example of a replacement part. Full exhaust systems installed on vehicles that did not originally contain a catalyst and whereby the design allows the reinstallation and original function of any other emissions control related components are also considered replacement parts. Parts that alter the emissions control related performance from the original part they are replacing, These parts may have catalysts in them but they perform differently from the original equipment part or they may require the alteration or elimination of other emissions related control components such as oxygen sensors.

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. Thanks for shopping with us!
