Description
The FMF Factory 4.1 RCT (Resonance Chamber Technology) exhaust system is engineered to provide maximum power gains across the entire power range. Its patented core shape lowers decibels while maintaining optimal power output. Internal ducts increase internal volume, improving exhaust flow and overall engine performance.
