FMF - Gnarly Pipe (Yamaha)

FMF – Gnarly Pipe

The FMF Gnarly Pipe is built for riders who like to push deep into the woods, hammer rocky climbs, and muscle through terrain that eats lighter pipes alive. Designed for 200cc to 500cc two-strokes, this pipe turns your bike into a torque monster — more pull at low rpm, smoother mid-range power, and that tractor-like grunt that gets you out of sketchy situations.

Made from super-strong 18-gauge steel, the Gnarly is tough enough to take real off-road abuse — rocks, logs, and crashes are just part of the ride. It’s electro-nickel plated for a durable, chip-resistant finish that won’t fade or rust, no matter how many muddy washes you slog through. O-rings are included, so installation is straightforward and airtight.

Why We Like It:
This is the pipe that saves your day when the trail gets ugly. It gives your two-stroke the kind of low-end torque you usually only find on big 4-strokes, making it easier to crawl over roots, rocks, and technical climbs without constantly clutching. It’s basically bulletproof and sounds awesome doing it.

Why It’ll Work for You:
The Gnarly Pipe helps your bike put power where you actually need it — down low. That means it pulls stronger at slow speeds, giving you more control in tight sections and better traction when things get slick. And because it’s built from heavy-duty steel with a nickel-plated finish, you can drop it, scrape it, and ride it hard without worrying about damage.
