Factory 4.1 Silencer - high-end silencer from FMF, one of the best silencers that are currently available on the market.
The silencer is made of high quality materials normally used in the aerospace industry and provides a significant power increase throughout the entire rpm range. The weight is shifted towards the center, which leads to better handling, which is especially important when offroad riding.
Fits with original head pipe (Slip-On).
The titanium version is very light, which adds an additional positive effect on acceleration and handling.

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.

- 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.
Silencer for motorcycle, scooter, moped
The silencer or muffler, is an essential part of the exhaust a two-wheeler. Its main function is to reduce the noise produced by the exhaust gases as they exit the engine, thus preventing unnecessary noise pollution.
How does a silencer work?
The silencer is usually a tube with perforated internal chambers that are surrounded by a sound-absorbing material. As exhaust gases enter the muffler, they pass through the openings in the walls of the pipe and are then absorbed by the silencer wool.
Silencer Maintenance
Should you notice that your two-wheeler is getting louder and louder, it's time to replace the insulation wool and exhaust gaskets. Maintenance is relatively easy and requires only a few tools.
If you regularly maintain your motorcycle or scooter, we recommend purchasing an exhaust plug to maintain the effectiveness and life expectancy of the insulation material.
