FMF - Powercore 4 Slip-On Muffler (Honda)

Looking to wake your Honda up without dropping race-system money? The FMF Powercore 4 Slip-On is that sweet spot between affordability and real performance. Designed using FMF’s top-tier race exhaust tech, it smooths out your bike’s power delivery and adds muscle through the low and midrange — right where you actually ride. You’ll feel stronger throttle response and better torque when you crack it open, plus that deep FMF tone that makes every twist more fun.

Built from stainless steel and aluminum, the Powercore 4 can take a beating while keeping things light. The finish looks clean, the fit is tight, and installation’s a breeze — a bolt-on upgrade that instantly makes your bike feel sharper and sound meaner.

Why We Like It:
It’s the definition of “simple and effective.” You bolt it on, and your Honda immediately feels livelier — stronger drive out of corners, smoother roll-ons, and a throaty sound that hits the right balance of power and control. It’s that perfect FMF blend of reliability, tone, and performance.

Why It’ll Work for You:
This system adds usable power where it counts — in that low-to-mid range zone you’re always working in. The Hi-Flo core and enhanced sonic evacuation help your engine breathe easier, giving you cleaner throttle response and more grunt through tough terrain or tight trails. And because it’s built from stainless and aluminum, it lasts season after season without weighing you down. Whether you’re trail riding, practicing, or just chasing that extra snap, this muffler delivers the boost you’ll actually feel.
