Show original supplier description
The FMF Racing Factory 4.1 RCT full exhaust system is engineered with FMF's Resonance Chamber Technology™ for optimized performance. Its shorter overall length enhances durability and aids in mass centralization by moving the muffler closer to the motor. Constructed from aerospace-grade aluminum and proprietary blend stainless steel, this system meets exacting specifications. It includes a screen insert spark arrestor and a quiet insert that meets AMA Professional Sound Requirements.
