Reviews

The development of the RS-4 silencer paid huge dividends in 2010 with Ryan Dungey winning the AMA 450 Supercross and Motorcross Championship series as a rookie in that year and repeating his performance in 2012 with the Yoshimura backed GEICO Honda team winning both 250 Supercross Lites titles. 

That same R&D has been dedicated to developing the current generation of RS-4 silencer which features a unique design which provides the perfect combination of power and a quieter exhaust. The RS-4 silencer consists of an Aluminium silencer, pentagonal shaped sleeve, stainless steel tail pipe and carbon end cap and has many features including a Poly-resonant duplex chamber which aids noise reduction, a two-staged stepped baffle and a USFS 94DB and 2M max noise baffle insert.
