FMF Gnarly Pipe — Yamaha YZ250 (1999-2026), Yamaha YZ250X (2016-2026), 2-Stroke

The Gnarly pipe focuses on increasing the lower RPM horsepower and torque to get you out of the toughest terrain. When you're looking to add 4-stroke tractor-like torque to your 2-stroke and you need a pipe to withstand the harsh elements, this is the pipe for you. Strong and rugged, the Gnarly dishes out handfuls of torque and bottom-to-mid range pull needed for late model 200cc through 500cc machines and the rigors of the off-road domain.

• Super-strong 18-gauge steel construction
• Electro-nickel plated for a non-chip finish that won't discolor
• Maximum low-end boost — 4-stroke tractor-like torque
• Designed for the rigors of off-road and enduro
• Most imitated expansion chamber design in the world

Fitment: 2-stroke bike specific — fits the following models:

• Yamaha YZ250 (1999-2026)
• Yamaha YZ250X (2016-2026)

This is a 2-stroke exhaust. It is engineered for the 2-stroke engine architecture above and physically will not fit a 4-stroke bike. Verify your engine type before purchase.
