Yoshimura RS-4 Carbon Fiber Slip-on Exhaust System
Yoshimura R&D has developed an evolutionary new exhaust system for the exciting new Kawasaki Ninja ZX-6R. The all-new Yoshimura RS-4 was designed after extensive testing and the results are profound.
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 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. The RS-4 muffler features a new front cap design that functions as a polyresonant chamber. This design makes for a quieter muffler with improved mid to top end power.
