The FMF Gnarly Torque Pipe, manufacturer part number 025004 and vendor part number 78-1504, is designed to deliver increased low-end boost for compatible KTM two-stroke motorcycles. This heavy-duty expansion chamber is engineered for late-model 200cc-and-up applications and provides dependable performance for trail, enduro, motocross, and off-road riding.
Built with an 18-gauge steel body, the FMF Gnarly Torque Pipe is made to withstand the impacts, vibration, and demanding conditions associated with off-road use. Its electro-nickel-plated finish helps resist chipping and discoloration while maintaining a clean appearance through repeated riding and exposure to the elements. The pipe is a direct-fit performance replacement for the specified KTM applications and is intended to work with the motorcycle’s existing exhaust system components.
