    If you're a rider looking for a silencer that's packing stellar looks and increased performance from a staple brand in motorsports, the FMF Factory 4.1 RCT Aluminum Silencer with Carbon End Cap and Side Panel is an option that we think sits close to the top of the class.

    FMF distinguishes their 4.1 RCT from other silencers from the start by using premium materials and a refined design developed over years of industry experience. Features like FMF’s unique Resonance Chamber Technology™ (RCT), a specialized chamber that sits at the front of the slip-on, lowers your exhaust decibel level so it complies with FIM 2M max sound tests and the stringent AMA sound requirements so you can get onto any trail and into any race where noise level regulations are enforced.

    While the RCT lowers sound, what's better is that it won't eat up your bike's power either. In Fact the RCT chamber design refines and enhances exhaust pressure to give your bike gains throughout the rpm range. Power increases are tunable as well with the end cap housing FMF's new Rapid Tuning System (RTS) that lets you swap between race tips (sold seperately) and the 94 db Quiet Core insert. With this level of performance and versatility FMF's Factory 4.1 RCT Silencers really do serve as an excellent option for all types dirt and off-road riders.

    Specs:
  • Comes with replacement "flat" side panel
  • Premium aluminum alloy canister body
  • Genuine carbon fiber composite end cap
  • Rapid Tuning System (RTS) allows for swapable end cap inserts (sold seperately)
  • Compatible with FMF and OEM headers
  • Resonance Chamber Technology (RCT) lowers sound and refines exhaust gas pressure
  • Increases performance throughout the rpm range
  • Efficient design centralizes mass and makes silencer body less prone to damage in a crash

  • Spark arrestor included and pre-installed in silencer

Nice pipes man!
I bought this slip on for my '16 CRF450R. Wanted to get rid of the dual setup. This pipe is about 1/3 of the weight of the dual assembly i'd guess. Sound is pretty ferocious without the spark arrestor, the included spark arrestor is easy to install and tones down the exhaust note a fair bit, closer to stock but throatier overall. The install was a breeze, took me maybe 15 minutes. There is no clamp where it slides onto the header just an FYI to others. The fit is decently snug, a little high temp silicone took care of any leakage, if you even opted to use it. Overall I'm please with the fit, finish and the sound. I haven't had a chance to ride with it but i'm sure it will open the engine up a little more. The side panel fit great as well, always a good thing to shed some pounds off the bike!
