The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology™ both internally and externally.
The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology™ both internally and externally.
It starts at the center with a new core - a patent pending shape enhances and refines the exhaust pressure wave for optimal power output while lowering the sound level.
