  • 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 level
