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 a pentagonal shaped muffler that features a carbon fiber cone end-cap, two staged stepped baffle and striking good looks. 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.
