FMF Factory Fatty Exhaust Pipe — KTM SX 150 2011–2015 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. Fits: KTM SX 150 (2011–2015); KTM XC 150 (2011–2015); KTM SX 125 (2012–2015); Husqvarna TC 125 (2014–2015); Husqvarna TE 125 (2015–2016). Specifications — material: Steel, weight: 1,55 kg. 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: 025121.
