Frequently Asked Questions

Q: Is this silencer legal for riding in National Forests?
A: Yes, it features the FMF "Turbine Dampening System," which is a U.S. Forest Service legal spark arrestor.

Q: Does this silencer improve performance over the stock exhaust?
A: Absolutely. The straight-through design provides a more unrestricted flow, leading to increased power gains throughout the powerband compared to most restrictive stock units.

Expert Pro-Tip: Since you are running a 2-stroke, check your silencer packing every 15-20 hours of hard riding. If the packing is blown out, your bike will lose low-end torque and the canister will get significantly hotter. Repacking it regularly keeps the power crisp and protects the aluminum casing.
