Fitment: This FMF pipe fits the 2016–2018 KTM 125 SX, 2017–2018 KTM 150 XC-W, 2016–2018 Husqvarna TC 125, and 2017 Husqvarna TE 150.

Construction: FMF electro-nickel plates its pipes for a durable, non-chip finish designed to resist discoloration during normal use. The coating provides a clean appearance while helping protect the pipe from wear associated with off-road riding. This Factory Fatty design is built for riders seeking strong, broad power delivery without limiting the pipe’s practical trail or motocross performance.
Factory details: Unlike the electro-nickel-plated pipes, the Factory pipe has hand-pounded welds and no coating, following the appearance and construction style of works racing bikes. The FMF brand is recognized for application-specific exhaust components engineered for performance-focused motorcycle use.
