Yoshimura RS-2 Signature Series Slip-On Exhaust
Yoshimura Signature Series exhaust components are the answer for riders faced with ever-tightening noise and emissions regulations at the federal level. All Signature Series components are independently tested, documented, and marked as required by state and federal regulations as CARB/EPA-compliant.
The RS-2 slip-on muffler is a potent and versatile design that evolved from Yoshimura's original TRC, engineered to provide increased and better power delivery. With a different pyramidal shape that increases volume over traditional muffler shapes, the RS-2 is a quieter system with a larger core and outstanding performance.

Questions & Answers
Do you need to re-jet to use this slip on.
While it's not required, if you want to get the best possible throttle response and engine power output, you should certainly re-jet your bike upon installation of this, or any other exhaust component we sell. This holds true for headers, slip-on mufflers or full exhaust systems. Of course, you can give it a try without re-jetting and see how the bike performs, but if you want to maximize your investment in an exhaust, again - we recommend adjusting fueling.
We have a variety of Dynojet Carburetor Jet kits available that'll work with the RS-2 slip-on muffler. Each kit includes everything you need to set up fuel delivery for that slip-on and also, clear instructions as to how to fine-tune the carburetor to get the best that exhaust has to offer.
