Description
Yoshimura has been the official exhaust supplier to Team Honda Red
Bull Racing for several years now. All of that experience has helped
Yoshimura in making an exhaust that compliments an already great bike.
The RS-4 not only increases power and is light, but it also has a lower
centralized mass coefficient to provide better handling. Additionally,
an overall improvement to the big Honda's power delivery was also
realized.
The RS-4 is pentagonal shaped muffler that features a carbon fiber
cone end-cap, two-staged stepped baffle and striking good looks. A
tapered header pipe design is used for optimal flow and performance.
The RS-4 muffler features a new front cap design that functions as a
poly-resonant chamber. This design makes for a quieter muffler with
improved mid to top end power.
An AMA-approved sound insert comes installed in the muffler, along with a 2 meter-Max insert in the box.
