Yoshimura 18-21 CRF250R RS-9T FS SS/SS/CF Tips

All Signature series exhaust are tested, documented and marked with appropriate EPA noise emissions labels

Dual-muffler design exhaust system

Achieves maximum performance, mass centralization, and rider usability

Systems feature three-stage tapered headpipe for the best power gains, better throttle response and power delivery

Vertical divider splits the exhaust gases more evenly for smoother flow to the mufflers for better mid-top power and throttle response

Parallelogram-shaped muffler bodies increase muffler volume over the stock system for even crisper throttle response and reduced noise levels

Systems meet AMA noise sound regulations right out of the box (AMA 2-Meter Max and Amateur 94 dB sound compliant)

Muffler inserts are tunable to adjust power delivery and noise levels
