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.

Compatible with most modern Husqvarna off-road and dual-sport models. Includes USFS-approved spark arrestor.

Breathe Easy, My Civic’s Engine Just Got a Spa Day!
Let’s talk about the Premium Engine Air Filter that’s compatible with my Honda Civic—because every car deserves a little TLC, right? Installing this filter felt like giving my engine a refreshing breath of fresh air (pun totally intended). My old filter was so clogged it could’ve doubled as a dust bunny in a horror movie. But with this new filter, my Civic is running smoother than ever! It’s like my car took a deep inhale and said, “Ahhh, that’s the stuff!” Now I’m cruising down the road, and my engine sounds happier than a kid in a candy store. The installation process was easier than finding a parking spot at the mall (and we all know how impossible that can be). I popped it in, and just like that, my car was ready to tackle the open road—or at least the next drive-thru. If you care about your car and want to keep it running like a champ, this air filter is a no-brainer. It’s affordable, easy to install, and your engine will thank you for the upgrade. Trust me; your Civic deserves the best air it can get—because happy engines make for happy drivers!
