Exhaust Header FMF Gold Series Gnarly — Beta RR 300, RR 250, RX 300 2020–2026 (2T)

Description

The FMF Gnarly is a two-stroke pipe built for bottom-end torque. It's the choice for terrain where you don't ride the revs — rocks, roots and steep climbs, where you need the motor to pull from down low and not stall. Made from heavy 18-gauge steel, thicker than the Fatty — this pipe is built to take hits. O-rings are included. Intended for late-model machines in roughly the 200 to 500 cc range. Fits: Beta RR 300 (2020–2026); Beta RR 250 (2020–2026); Beta RX 300 (2021–2024). Specifications — material: Steel, finish: Nickel-Plated. Note: does not meet the 2025 FIM sound limit — intended for practice and closed courses, not for FIM-sanctioned racing. Delivery 5–8 working days. SKU: 025270.
