Yoshimura RS-4 Pro Exhaust System

Yoshimura RS-4 Pro Exhaust System

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 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 polyresonant chamber. This design makes for a quieter muffler with improved mid to top end power.

Features:

• Titanium Head pipe
• Carbon fiber end cap
• Your choice of titanium or carbon fiber muffler sleeves
• 99db sound insert installed

Optional 94db (AMA legal) and 96db sound inserts available separately.
