FMF 022069 Gnarly 2-Stroke Expansion Chamber Pipe

The FMF Gnarly 2-Stroke Expansion Chamber Pipe (022069) is engineered for off-road riders who demand serious bottom-end and mid-range torque from their two-stroke machine. Designed specifically for late-model 200cc through 500cc two-stroke engines, this pipe transforms the power delivery of your bike into the kind of strong, tractable pull needed to conquer gnarly trails, tight woods, and demanding off-road terrain.

Key Features:

• Maximum low-end and mid-range torque boost — delivers 4-stroke tractor-like power characteristics to your two-stroke engine
• Heavy-duty 18-gauge steel construction — significantly thicker than standard pipes, built to withstand the punishment of hard off-road use
• Electro-nickel plated finish — FMF's signature non-chip, non-discoloring surface treatment, the most imitated expansion chamber finish in the industry
• Made in the U.S.A. — American-designed and manufactured to FMF's exacting performance standards
• Header O-rings included — everything needed for a proper, leak-free installation is in the box
• Closed-course competition use only — not intended for street use

The FMF Gnarly pipe is the go-to choice for GNCC, enduro, and off-road riders who need a rugged, torque-focused exhaust system. Its thicker steel body shrugs off rock strikes and trail debris while the expansion chamber geometry works to push power exactly where you need it — out of tight corners and over technical obstacles. If maximum low-end grunt and bulletproof durability are your priorities, the FMF Gnarly pipe delivers.
