Yoshimura RS4 Full System SS-AL-CF

The development of the RS-4 system 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 full system which features a unique design which provides the perfect combination of power and a quieter exhaust. The RS-4 full system consists of silencer, pentagonal shaped sleeve,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. The silencer for this system comes in a variety of finishes including Aluminium, Titanium and Carbon and the header coming in a choice of Titanium or Stainless Steel. This system also comes with a choice of either the spark arrester noise baffle insert or 94DB and/or 2M Max noise baffle insert both USFS approved.
