The Factory 4.1 RCT exhaust system incorporates FMF's Resonance Chamber Technology™ both internally and externally.
The overall length of the engine is reduced, making it less prone to damage in the event of a fall and better suited to Factory Forward Engineering - the silencer is positioned closer to the engine for better centralisation of the masses
Factory 4.1 RCT is manufactured using only aerospace-grade materials to exacting specifications and is 100% produced in the Southern California factory
