Features:

• RS-12evo carbon fiber end cap: It was time to enhance the look of the RS-12. Introducing RS-12evo carbon fiber end cap, the next level, represents an unrelenting pursuit of form and function from our R&D engineers at Yoshimura.
• All-new Hydroformed Stainless Muffler: RS-12evo is an all new hydroformed stainless steel muffler design that allows for the most efficient use of the area next to the airbox, subframe and shock creating a custom tailored fit that no others have.
• The fitment is engineered to nest with the stock side panel perfectly. Efficiency is one thing, but the sick look of the styling on the RS-12evo muffler is second to none.
• Precision Taper Fit: Precision Taper Fit sound inserts are a patent pending system that allows for easy removal and installation of sound inserts and spark arrestors with RS-12 and RS-12evo mufflers.
• Includes USFS approved spark arrestor: The RS-12evo slip-on for the Honda CRF450R is designed, developed and made in the USA
