Product Details

The Factory 4.1 RCT in anodized finish — FMF's race-proven RCT pipe with the option to match your bike's color theme. Same Resonance Chamber Technology, RTS tuning, and quieter-than-stock operation as the rest of the 4.1 RCT line.

  • FMF Resonance Chamber Technology (RCT)
  • Anodized finish to color-match the bike
  • Rapid Tuning System (RTS)
  • Lighter and quieter than stock
  • Made in Southern California

Fitment: 4-stroke bike specific — fits the following models:

  • Yamaha YFZ450R (2009-2026)
  • Yamaha YFZ450X (2010-2011)

This is a 4-stroke exhaust. It is engineered for the 4-stroke engine architecture above and physically will not fit a 2-stroke bike. Verify your engine type before purchase.
