FMF Factory 4.1 RCT Titanium Anodized Full System — Husqvarna FC 250 (2016-2018), Husqvarna FC 350 (2016-2018) + 20 more, 4-Stroke
Product Details

The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology (RCT) — both internally and externally. A patent-pending shape enhances and refines the exhaust pressure wave for optimal power output while lowering the sound level. Constructed from aerospace-grade titanium with a carbon end cap, the system is shorter, lighter, and quieter than stock.

  • FMF Resonance Chamber Technology (RCT) for power + quieter operation
  • Aerospace-grade titanium construction with carbon end cap
  • Shorter overall length — less crash-damage exposure, mass centralized
  • Rapid Tuning System (RTS) for easy insert and spark-arrestor swaps
  • Quieter than stock with huge weight savings
  • Manufactured 100% in Southern California

This is a 4-stroke exhaust. It is engineered for the 4-stroke engine architecture above and physically will not fit a 2-stroke bike. Verify your engine type before purchase.
