FMF Powercore 2 Shorty Silencer 024019 — Yamaha YZ80 / YZ85 1993-2026

Product Description

Give your mini racer an unfair advantage out of the starting gate with the FMF Powercore 2 Shorty Silencer 024019. Widely considered the ultimate exhaust upgrade for tight supercross tracks and stadium-style riding, this performance slip-on is engineered specifically to maximize bottom-end power. By shortening the overall length of the aluminum canister and internal core, FMF optimizes exhaust pulse tuning to deliver a crisp, immediate throttle response and a significantly harder low-to-mid range power hit.

Designed to take the abuse of aggressive off-road and motocross racing, this high-performance silencer features an oval aluminum muffler canister paired with a durable stainless steel mid-pipe and a sleek conical end cap. It strips away top-heavy factory rear weight to give your motorcycle improved handling agility in deep ruts and berms. Whether you are attacking a technical indoor track or ripping through backyard tracks, this bolt-on modification delivers that signature sharp, snappy two-stroke bark that leaves the competition behind.

Frequently Asked Questions

Q: What is the main difference between this Shorty silencer and the standard Powercore 2?
A: The standard Powercore 2 is designed to provide an even, smooth boost across the entire powerband. The Shorty silencer uses a condensed internal core that purposefully builds backpressure faster, resulting in a much more aggressive power hit directly off the bottom end for faster corner exits.

Q: Does the FMF Shorty silencer require specific maintenance?
A: Yes, because shorty silencers contain less internal space, the fiberglass packing material will absorb unburnt oil and fuel slightly faster than standard models. To maintain maximum performance and avoid a harsh exhaust tone, we recommend changing the packing every 15 to 25 hours of operation.

Expert Pro-Tip: When replacing your two-stroke muffler, never reuse a degraded or loose rubber exhaust joint boot. A leaking joint bleeds essential backpressure, causing a sluggish low-end response and leaving messy black oil trails over your subframe. Always mount a fresh silicone coupling sleeve and apply a thin layer of high-temperature RTV silicone sealant around the slip joint connection to guarantee an airtight seal.
