Notes and Safety
FMF Factory 4.1 Slip-on
The Factory 4.1 silencer from FMF is the brand's top model and was developed using the latest cutting-edge technology by Don Hemler's team in collaboration with the best riders in the world.
Factory 4.1 technology and performance
The Factory 4.1 RCT features a patented Resonance Chamber Technology™, which uses a sophisticated channel system to increase the internal volume and reduce the overall length of the ESD to the shortest possible length, resulting in less damage in the event of a crash. The silencer is moved to the center towards the engine, which makes the entire motorcycle more stable. Noise emissions are minimized without any loss of power.
The silencer is made from aerospace-grade materials, making it strong and lightweight.
In terms of performance, FMF guarantees performance increases across the entire RPM range. The brand's exhausts are known for their improved response at low engine speeds.
Thanks to the "Rapid Tuning System" you can easily remove the db-killer.
- Made from aerospace-grade titanium, aluminum and carbon
- Compatible with original or FMF manifolds
- Low weight
- Performance increase at all RPMs
- Easily removable DB Killer
- Simple installation
For maximum performance with a noise level that meets the required standards, we recommend a combination with the MegaBomb header from FMF.
