Exhaust Header FMF Fatty — Yamaha YZ 85 SW, YZ 85 LW 2019–2026, carbon (2T)

The FMF Fatty is a two-stroke pipe that broadens the whole usable powerband — it adds power evenly rather than in one spike. Throttle response improves and the motor pulls further into over-rev. Tru-Flo stamping holds the exact profile and a precise fit on stock mounts. A versatile choice for tracks, trails and open desert alike. Fits: Yamaha YZ 85 SW (2019–2026); Yamaha YZ 85 LW (2023–2026). Specifications — material: Carbon Steel, finish: Nickel-Plated. Note: does not meet the 2025 FIM sound limit — intended for practice and closed courses, not for FIM-sanctioned racing. Delivery 5–8 working days. SKU: 024072.
