Carbon Cap","description":"The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology™ both internally and externally. In addition, we achieve a shorter overall length that is less susceptible to crash damage and complementary to our Factory Forward Engineering - moving the muffler closer to the motor to centralize mass. The Factory 4.1 RCT is constructed from only aerospace grade materials that meet our exacting specifications and is manufactured 100% at our Southern California factory.\n\u003cul\u003e\n  \u003cli\u003eHighest-quality proprietary blend of alloy grade titanium\u003c\/li\u003e\n  \u003cli\u003eBlue anodized titanium muffler with carbon end cap\u003c\/li\u003e\n  \u003cli\u003eMassive power gains throughout the RPM range\u003c\/li\u003e\n  \u003cli\u003eRapid Tuning System (RTS)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe FMF Racing Factory 4.1 RCT slip-on muffler is engineered for Yamaha YZ250F models from 2010 to 2013, delivering exceptional power gains and optimal performance. Crafted from aerospace-grade titanium, this muffler features a proprietary alloy blend that ensures durability and lightweight handling. The blue anodized titanium exterior combined with a carbon fiber end cap provides a sleek, high-performance aesthetic. The incorporation of FMF Resonance Chamber Technology™ enhances exhaust flow and sound quality, resulting in significant performance improvements across the entire RPM range. Its shorter length design minimizes vulnerability to crash damage and complements Factory Forward Engineering, relocating the muffler closer to the engine to centralize mass and improve handling. The Rapid Tuning System (RTS) allows for quick and precise adjustments, making it easier to fine-tune the exhaust for different riding conditions. Built entirely in Southern California, this muffler meets strict EPA standards and is compliant with all relevant regulations, ensuring environmentally friendly performance without sacrificing power.
