FMF Factory Fatty Exhaust Pipe — KTM SX 85 17/14 2003–2017 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 85 17/14 (2003–2017); KTM SX 85 19/16 (2003–2017); KTM SX 105 (2007–2011); Husqvarna TC 85 17/14 (2014–2017); Husqvarna TC 85 19/16 (2014–2017); KTM XC 105 (2008–2010); KTM XC 85 (2008–2009). Specifications — material: Steel. 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: 025090.
