Product Details

The Factory 4.1 RCT in stainless steel construction. Same Resonance Chamber Technology and power gains as the titanium system, with a stainless mid-pipe and muffler body for budget-friendly toughness. Shorter length, lighter than stock, and quieter than OEM with FMF's Rapid Tuning System.

  • FMF Resonance Chamber Technology (RCT)
  • 304 stainless steel construction — rugged and corrosion-resistant
  • Shorter overall length for mass centralization
  • Rapid Tuning System (RTS) — sound insert and spark arrestor swaps
  • Quieter than stock with weight savings

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

  • GasGas EX 250F (2021-2023)
  • GasGas MC 250F (2021-2023)
  • Husqvarna FC 250 (2019-2022)
  • KTM 250 SX-F (2019-2022)
  • KTM 250 XC-F (2019-2022)

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.
