35 years of racing experience: The FMF factory pipes have been specially developed for the hardships of off-road life. That's why they're made from high-quality, extra-thick, hard-wearing sheet steel. An elegant appearance is ensured by the nickel-plated, stainless, polished surface. For years and years. Broader and more usable rev range. Fat torque curve for optimal rideability. Minimal weight and maximal performance. Made from rugged steel. Nickel-plated, rust-free and polished surface. Higher top speed. More traction, better control when accelerating. Including O-rings. Note: For a perfectly tuned and performance-optimized overall system, best recommended combination with an FMF factory silencer. Husqvarna PowerParts P/N: 23305907000.
