§ 02 / About this part
What it is
The FMF EXHAUST FACTORY FATTY PIPE, full systems. Stocked by Iron Offroad, the UK MX hard parts specialist.
This expansion chamber broadens the powerband across the entire rev range. It sits at the heart of your 2-stroke exhaust tract. The raw finish requires regular maintenance to prevent corrosion in typical UK riding conditions. Wipe it down with a light oil after every wash. It replaces the restrictive OEM unit to improve throttle response and over-rev. Fitment is model-specific and uses your existing mounting points. Check your O-rings and springs during the swap. This is a staple for track or hard enduro use where mid-range pull is vital.
