FMF Q4 HEX S/A Slip-On — Kawasaki KX450F (2024-2026), Kawasaki KX450X (2024-2026), 4-Stroke
Product Details

The Q4 HEX is FMF's quietest 4-stroke slip-on — a hexagonal canister with sound-attenuating internal architecture and integrated spark arrestor. Built for noise-restricted tracks and U.S. Forest Service trails where you need quiet, low-decibel operation without losing performance feel.

  • Quietest FMF 4-stroke slip-on
  • U.S. Forest Service approved spark arrestor
  • Hexagonal aluminum canister
  • Stainless steel endcaps
  • Ideal for noise-restricted tracks and off-road

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.
