    The FMF Factory-4.1 RCT Aluminum Silencer features a bigger volume can which can utilize more packing material for better performance and longer lasting low output sound volume. The RCT in the front end of the exhaust is another huge added gain for sound and performance. The FMF Factory-4.1 RCT Aluminum Silencer is sound compliant with the FIM 2M Max sound test. The design of the FMF RCT exhaust was to offer a look that really fits the complex lines that many of the manufactures are leaning towards.
  • Incorporating the latest in Resonance Chamber Technology.
  • Patented core shape lowers sound level while maintaining maximum power output.
  • Patented canister shape increases internal volume for more sound absorbing material.
  • Patented chamber design to enhance and refine exhaust pressure.
  • Factory Forward Engineering centralizes mass and is less prone to crash damage.
  • Tuned exhaust with optimized core specifications for each application.
  • Innovative Carbon Fiber rear end cap for simple installation of tuning tip inserts or spark arrestor.
  • Meets AMA and FIM sound requirements.
  • Spark arrestor included in muffler.
  • Built 100% in the U.S.A. at FMF’s state-of-the-art-factory.
  • Maintenance made easy with the removal of 4 screws on the front end cap.
  • Compatible with stock head pipe or FMF head pipe.

definite improvement over OEM

Comments On Aug 07, 2015:Sounds awesome which is a good thing in the thick woods & a non directional track. Greatly increased low & mid range power and throttle response over the OEM SX silencer.

Good, not great

Comments On Jun 10, 2015:Overall I'm pretty happy with this slip-on. It most definitely improves the sound by giving it a much louder and throatier sound compared to stock. I'm using it with the stock header, but I did remap the ECU after installation. I've got to say, I didn't feel THAT big a difference in power over stock. The bike definitely runs richer after the remap and it might pull a little longer overall after installing this slip-on, but it's not a night and day type thing. The only real negatives were the lack of any type of sealing gasket where the muffler slips on to the header pipe (had to use high temp gasket maker) and the fact that the can itself is not completely sealed where it is riveted together (i noticed some water being displaced from there upon start up after the first wash).

Awesome Exhaust!

Comments On Jan 15, 2015:So much better sound, and definitely seems to be a bit more power. Using it with the FMF Power Bomb Header Pipe.

Comments On Jul 12, 2014:Oh Yeah! The install changed the stock tune so be prepared to buy a tuner. I have to run spark arrestor for many races and this one comes with it. The sound is not obnoxious and pretty close to stock. I'm very happy with this purchase.
