Spark arrestor screen insert included. For closed course competition use only. The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber TechnologyT 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. Here at Moto25, we don't just sell parts and accessories.
