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:
This slip-on gives you the perfect balance of power, noise control, and durability. It helps your Husky run smoother, stronger, and quieter — perfect for riders who hit technical trails, forest routes, or sound-sensitive riding areas. You’ll feel the torque increase immediately, without the ear fatigue.

Perfect for my application. I installed mine in my metal garage cabinets to allow me a place to store equipment battery chargers out of sight.

3 inches plus!
Color: Black, Size: 6FT
It works well BUT you will need a little more than a three inch opening. I ordered this as a replacement for a plain plastic grommet. I had to buy an attachment for my drill to make the hole a tad bigger and smooth out any bumps in the hole.
