FMF - Powercore 4 Hex Slip-On Muffler (KTM)
If you want your KTM to pull harder, sound meaner, and feel livelier without spending a fortune, the FMF Powercore 4 Hex Slip-On is the perfect upgrade. FMF took lessons from their top race systems and packed them into this affordable, easy-to-install exhaust — giving you stronger torque, better throttle response, and that unmistakable FMF tone.
Built with a stainless steel mid-pipe and aluminum canister, the Powercore 4 is lightweight yet tough enough for years of riding. Inside, FMF’s Hi-Flo core design and enhanced sonic evacuation push air through more efficiently, unlocking smoother power and faster revs through the entire range. It’s a clean, factory-style setup that gives your KTM a sharper sound and feel on any terrain.
Why We Like It:
It transforms the bike’s character instantly. The throttle feels crisp, the midrange wakes up, and you get that deep FMF growl that sounds right without being obnoxious. It’s durable, simple to install, and gives your KTM that pro-level performance bump without needing a full system.
Why It’ll Work for You:
This slip-on adds power where you’ll feel it most — off the bottom and through the midrange. That means stronger pull out of corners, smoother throttle response in technical terrain, and more confidence when you roll on the gas. It’s built from stainless and aluminum for longevity, uses FMF’s proven Hi-Flo design for max airflow, and includes a removable spark arrestor so you’re always trail-ready.
