Product Description
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

jeff sniadach port orange,  FL yosh pipe The pipe is awesome. It delivers more power down low and pulls through the gears thru the top end where the 09 crf 450 had a tendency to die out. Well worth the money.
