Boost your 2-stroke’s low-end drive with a pipe designed for real terrain. The FMF Gnarly Pipe is built to increase lower-RPM horsepower and torque, giving you that tractor-like pull when conditions get technical. Whether you’re crawling through rocks, roots, mud, or deep ruts, this pipe helps your bike respond with stronger bottom-to-mid power and improved rideability.
Designed specifically for the harsh demands of off-road riding, the Gnarly uses super-strong 18-gauge steel and a durable nickel-plated finish to better resist dents and abuse compared to thinner race-focused pipes. It’s an ideal choice when you want performance gains you can feel—without sacrificing durability.
Key features:
✅ Low-RPM performance focus – increases horsepower and torque down low to get you out of the toughest terrain
✅ Bottom-to-mid pull – aggressive torque delivery for better drive and control
✅ Heavy-duty construction – 18-gauge steel makes it truly “Gnarly”
✅ O-rings included – helps make installation and sealing easier

🔹 More usable power where you need it most – improved traction-friendly torque for technical off-road riding
