FMF Factory 4.1 RCT Slip-On Exhaust for Yamaha — 044400

The Factory 4.1 RCT Slip-On Muffler (044400) for Yamaha delivers power gains across the RPM range with a lighter, more compact design. It employs FMF Resonance Chamber Technology internally and externally to optimize exhaust flow while maintaining a refined, race-ready sound. The shorter overall length reduces crash risk and centralizes mass toward the engine for improved handling.

The blue anodized titanium can with a carbon end cap combines durability with a distinctive appearance that stays cool under demanding riding conditions. An integrated RTS (Rapid Tuning System) enables quick, on-the-fly adjustments to tune tone and flow to track conditions without removing the muffler.

• Materials: aerospace-grade titanium with blue anodized finish and carbon end cap
• Design: slip-on muffler designed specifically for Yamaha models; includes all necessary mounting hardware
• Performance: improved throttle response and engine efficiency across the RPM range
• Durability: constructed in FMF’s Southern California factory from high-spec alloys
