FMF – Q4 Hex Slip-On Muffler (Husqvarna)
When you want more performance without the noise, the FMF Q4 Hex Slip-On Muffler is the answer. Designed for serious off-road riders who demand power and compliance, the Q4 delivers real gains across the rpm range while keeping sound levels within USFS and FIM World Enduro regulations. Using a combination of intricate chambers, internal baffles, and proprietary multistage packing, FMF has created the quietest high-performance exhaust in the game.
Built to take a beating, the Q4’s rugged construction makes it ideal for enduro, dual-sport, and adventure riders who ride hard and long. It’s pounds lighter than stock, features an included spark arrestor, and delivers that signature FMF smooth power delivery — strong, predictable, and clean. Like all FMF systems, it’s handcrafted in the USA for riders who want dependable performance and quality.
Why We Like It:
It’s a true “quiet power” exhaust — strong where it counts, whispering when it matters. The Q4 keeps your Husqvarna fast and compliant without sacrificing feel, tone, or throttle response.
Why It’ll Work for You:

It helps your Husky run smoother, stronger, and quieter — perfect for riders who hit technical trails, forest routes, or sound-sensitive riding areas.
