Description
The FMF Factory 4.1 RCT exhaust is the result of years of collaboration with the best teams and riders. These exhausts provide maximum power increase over the entire speed range. Great exhaust with better engine response, optimized acceleration and higher maximum power at higher speeds.
The Megabomb header pipe provides an increased torque and reduces the noise level.
The models in titanium are also significantly lighter, which also benefits acceleration.
Cool Factory look plus top performance - super combination that will satisfy even demanding riders.
With DB-killer.
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.
