FMF Factory Line Titanium Kawasaki KX 450 2024
Why FMF?
FMF is one of the pioneers in the field of exhaust technology and has been developing high-performance exhausts for motocross bikes since 1973. FMF has always worked with professional riders and engineers to develop exhausts that compensate for the weaknesses of each model and deliver more horsepower across the entire power curve.
Features and benefits of the FMF Factory 4.1 complete system
The FMF Factory 4.1 gives every motorcycle an increase in performance across the entire power curve. The response is improved, the revving up is clean and linear and the power at high revs is increased.
The system consists of a Megabomb manifold, which provides more torque and a lower noise level, and a lightweight Factory 4.1 silencer, which releases horsepower at all engine speeds.
The titanium version also achieves a considerable weight saving.
- RCT technology (Resonance Chamber Technology)
- Minimal external dimensions to avoid damage and center the masses
- Aerospace quality materials
- RTS system (Rapid Tuning System) ensures easy installation
FMF Factory 4.1 Sound
FMF is aware of the impact of sound on motorcycling and offers the Factory 4.1 exhaust, which complies with FIM standards. This exhaust is therefore suitable for use in racing, as it complies with the permissible noise limits for sound level measurements.
TheDB killer / noise reducer is included.
Suitable models FMF exhaust:
- Kawasaki 450 KX from 2024
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.
Motorcycle Full exhaust
Even on motorcycles, replacing the original exhaust with a tuning exhaust can lead to more power or an improved performance, but above all a tuning exhaust has a better sound, since original exhausts often sound somewhat muffled.
Slip-on or full exhaust?
Replacing the complete exhaust has significant advantages over replacing the slip-on (muffler only) or header. If you choose a full exhaust system, you don't have to worry about the compatibility of the individual components.
Slip-ons usually fit on the original headpipes and headers fit on the original silencers, but nevertheless the installation of a full exhaust with silencer and head pipe perfectly matching out of the box, will get the best results with optimal performance and maximum power.
Repairinga full exhaust
If your original exhaust is getting too loud, you don't have to immediately replace it. We carry silencer wool, special rivets as well as springs, brackets and gaskets to bring it back to good working order.
If your exhaust is beyond salvage (for example, because it is bent after a crash), you can also use a matching slip-on that cost less than a complete exhaust.
