Increase performance across the power range with the FMF Fatty Expansion Chamber Pipe, manufacturer part number 024034 and vendor part number 78-1326. Designed for the Yamaha PW80, this aftermarket exhaust pipe is engineered to deliver a broad, all-around power increase for recreational riding and off-road use. Its power-focused design helps improve engine response and usable performance throughout the powerband.
Feature: The FMF Fatty pipe provides balanced power gains across the low, mid, and upper rpm ranges, making it a versatile choice for Yamaha PW80 riders seeking stronger overall performance. All applicable FMF pipes use electro-nickel plating for a durable, non-chip finish that resists discoloration. The factory-style pipe is the exception, featuring hand-pounded welds and no coating for a works-inspired appearance.
Feature: FMF offers multiple pipe designs for different riding needs, including Fatty for all-around power, Gnarly for increased low-end torque, and Factory Rev for stronger middle- and upper-rpm performance. This listing is for the Fatty configuration, intended to provide a well-rounded power increase rather than concentrating performance in one section of the powerband.
The FMF Fatty Pipe 024034 fits 1991 through 2000 Yamaha PW80 models. It is a direct-fit performance exhaust component for the listed application and is suited to riders who want improved engine character without selecting a specialized low-end or top-end pipe. Confirm the motorcycle year and exhaust configuration before installation.
