2004-2009 Yamaha YFZ450. A complete bolt-on full system that adds power and sharpens throttle response, with the unmistakable Yoshimura sound.
The RS-2 evolved from Yoshimura's original TRC muffler and was engineered for increased power and better power delivery. The pyramidal muffler holds more volume, which actually makes it quieter, while a larger core keeps it flowing.
✓ Features
- Signature Series RS-2 full system, SS-AL-SS construction (stainless header and tail pipe, aluminum muffler)
- Diamond-shape sleeve with a stainless steel cone end cap
- Maximized internal volume with a straight, single-core baffle
- USFS-approved spark arrestor included (SA-06-K)
- Optional low-volume insert (INS-08-K) and spark arrestor (SA-02-K) available
- Developed with the same high-tech data acquisition and GPS tuning Yoshimura uses on its race program
- Made in the USA
✓ What's Included
- One Yoshimura RS-2 Signature full exhaust system (stainless header, aluminum muffler, mounting hardware)
- USFS-approved spark arrestor (SA-06-K)
