Upgrade the exhaust performance of your Honda CRF125F with the FMF Powercore 4 Muffler Slip-On, manufacturer part number 041581 and vendor part number 79-2637. Designed specifically for the 2019-2026 Honda CRF125F, this slip-on muffler delivers improved exhaust flow, reduced weight, and durable construction for trail and recreational riding applications.
The latest Powercore 4 design uses a high-flow core with increased surface area to absorb more sound while allowing exhaust gases to move efficiently. Its extruded aluminum canister and stainless steel mid-pipe are built for strength and durability, with MIG/TIG-welded construction and advanced internal packing to support consistent performance.
Feature: The FMF Powercore 4 S/A includes a U.S. Forest Service-approved, maintenance-free stainless steel spark arrestor screen for compliant off-road use where required. The muffler is lighter, stronger, and more powerful than the stock exhaust system, making it a practical performance upgrade without replacing the complete exhaust system.
