FMF YAMAHA YZ250F 19-26 YZ250FX 20-26 WR250F 23-26 FACTORY 4.1 RCT TITANIUM ANODISED BLUE CARBON FULL SYSTEM

FMF YAMAHA YZ250F 19-26 YZ250FX 20-26 WR250F 23-26 FACTORY 4.1 RCT TITANIUM ANODISED BLUE CARBON FULL SYSTEM

The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology™ both internally and externally. In addition, FMF achieve a shorter overall length that is less susceptible to crash damage and complementary to their Factory Forward Engineering - moving the muffler closer to the motor to centralise mass. The Factory 4.1 RCT is constructed from only aerospace grade materials that meet FMF exacting specifications and is manufactured 100% at their Southern California factory.

FEATURES

  • Available in Blue Anodised Titanium Muffler with Carbon End Cap 
  • Massive Power gains throughout the RPM range.
  • Huge weight savings
  • New RTS (Rapid Tuning System)
  • Advanced engineering and patented design
  • Meets AMA/FIM 94dB sound requirement
  • Spark arrestor available for purchase
  • Use with FMF or stock/OEM header
  • Easily serviced for repacking
  • FMF uses the highest quality proprietary blend of alloy grade titanium made especially to FMF standards.

FMF Megabomb Headers are the ultimate performance upgrade header pipe you'll ever bolt onto your four-stroke dirt bike. The science behind the FMF Megabomb header is perhaps one of FMF's greatest engineering accomplishments yet, and considering the range of impressive products they've constructed throughout their time, that's saying something. You can bolt one of these bad boys on with an existing FMF Muffler and makes gains all the way up to a 3hp boost, which is incredible! Plus, the Megabomb Header pipe can actually reduce noise levels by as much as 1.5dB, so it's a win-win situation all around. The technology behind the Megabomb works to produce a higher low end to mid-range power gains, as well as broadening the mid to top-end power of your stock exhaust header.
