FMF Factory 4.1 RCT Exhaust System KTM 250 XCF-W / 350 XCF-W

The FMF Factory 4.1 RCT full system is constructed from aerospace-grade materials that meet FMF's exacting specifications and is 100% manufactured in their Southern California factory. The patented MegaBomb header design allows exhaust gases to expand, cool and ramp back up at a higher velocity. This results in torque gains typically associated with longer headers, and the healthy over-rev of a short header. The muffler itself is shorter than OEM mufflers, making it less susceptible to crash damage and complements the centralized mass design by moving it closer to the motor. The rear end cap was engineered for fast and easy tuning by utilizing a retaining ring to keep the standard and optional inserts in place.

Features:

  • Massive power gains throughout the RPM range
  • Huge weight savings over stock exhaust
  • RTS (Rapid Tuning System) for quick and easy track-side tuning
  • Removable spark arrestor included
  • Titanium MegaBomb Header
  • Quiet insert included (94db)
  • Weight: 5.5 lbs
  • Meets AMA and FIM sound requirements 
  • 100% made in the USA
