Exhaust Header FMF Gold Series Fatty — Yamaha YZ 125, YZ 125 X 2005–2021 (2T)

Description

The FMF Gold Series Fatty is an expansion chamber for two-stroke bikes. Its larger chamber volume broadens the usable powerband — it adds mid-range pull where you need it driving out of a corner, without giving anything up on top. The shape is dyno-tuned for each individual bike. Built from 19-gauge steel with a nickel-plated finish that takes rocks and salt far better than bare metal. FMF's Tru-Flo stamping holds the profile exactly, so the pipe drops onto the stock mounts without any pulling. Fits: Yamaha YZ 125 (2005–2021); Yamaha YZ 125 X (2020–2022). Specifications — material: Steel, finish: Nickel-Plated, configuration: 1-Into-1 System. Delivery 5–8 working days. SKU: 024049.
