FMF – Powercore 4 Muffler (Honda)

The FMF Powercore 4 Muffler brings race-bred performance to everyday riders — all without the race-bike price tag. Designed using the same engineering principles found in FMF’s top-tier systems, the Powercore 4 delivers noticeable gains in torque and horsepower, giving your Honda stronger pull through the entire rpm range. It’s the perfect upgrade for riders who want a real performance boost with FMF’s proven quality and durability.

Constructed from a combination of stainless steel and lightweight aluminum, the Powercore 4 is built to handle the demands of off-road and track riding alike. The champagne-anodized canister resists wear while giving your bike that clean factory look, and the advanced packing material extends performance life before repacking is needed. A removable spark arrestor is included for trail legality, and riders can add the optional 96dB quiet insert for sound-sensitive areas.

Why We Like It:
It’s simple, effective, and reliable — everything you’d expect from FMF. The Powercore 4 gives your Honda a stronger, deeper tone and an instant improvement in throttle response without adding unnecessary weight or complexity.

Why It’ll Work for You:
This muffler helps your bike make smoother, stronger power across the board, especially in low- and mid-range torque. It’s tough enough for everyday riding, easy to maintain, and comes trail-ready with a spark arrestor. Whether you’re racing, trail riding, or just want more punch out of your Honda, it’s a proven upgrade that won’t let you down.
