FMF Factory Fatty Exhaust Pipe — GasGas EC 250 2018–2019 and others (2T)

The FMF Factory Fatty is a two-stroke pipe built along the lines of the “works” cone pipes factory teams once ran. Compared to the standard Fatty it is lighter and tuned more aggressively. The body uses lighter 20-gauge steel, the header section stronger 19-gauge. The seams are hand-pounded so the internal transitions stay smooth and don't choke the flow.
