FMF - Factory 4.1 Complete System with RCT

The FMF Factory 4.1 RCT exhaust system is the most innovative exhaust to date produced by FMF.  Building exhaust since '73, it's safe to say that FMF has been in the game for quite some time and knows how to get the most performance out of their exhausts.  A patent pending shape enhances and refines the exhaust pressure for optimal power output while lowering the sound level.  The FMF Factory 4.1 RCT exhaust achieves a shorter length by moving the muffler closer to the motor to centralize the mass.  Manufactured 100% in Southern California and guaranteed to produce massive gains throughout the RPM range, the FMF Factory 4.1 RCT exhaust belongs on your bike today!!

Specifications

  • Available in Natural or Anodized Titanium muffler
  • Massive power gains throughout the RPM range
  • Quiter than stock
  • Huge weight savings
  • New RTS (Rapid Tuning System) makes for easy sound insert changes as well as adding US Forestry Approved spark arrestor
  • FMF uses the highest quality proprieatary blend of alloy titanium made especially to our standards

Comments about FMF - Factory 4.1 RCT Complete System (KTM):

The pipe is very light, and fit and finish is awesome! However, when sliding back to the rear of the bike to get traction your pants will scratch the FMF sticker badly! FMF needs to address this, makes a new pipe look old in a matter of minutes! Besides the sticker, very pleased with this exhaust!

            A great pipe. it fits easily, is very light compared to stock and the mid range power gains were excellent, it makes the bike easier to ride. The pipe was extremely loud without the silencer that is supplied which also was very easily fitted. It looks cool and I hope it is durable.

                  This exhaust is the best exhaust system ive brought by far. it is so easy to install, looks great, sounds great and has all the power from low end to flat out! the bike now handles very well with this product on, and feels as if its so light on the back end!
                  i don't think i could say a single negative comment about this system!
                  very pleased with this product, and would recommend strongly.
