FMF Powercore 4 Muffler with Stainless Steel Header for 2014–2018 Honda CRF125F, Part 041533

The FMF Powercore 4 exhaust system is designed for riders seeking improved exhaust flow, reduced weight, and durable performance on compatible Honda CRF125F motorcycles. This Powercore 4 model includes a stainless steel header and is engineered as a high-flow replacement for the original equipment exhaust. Its advanced core design provides greater surface area to absorb sound while allowing exhaust gases to flow efficiently.

Constructed with an extruded aluminum canister and a MIG/TIG-welded stainless steel mid-pipe, the FMF Powercore 4 combines strength with a lightweight design. Space-age internal packing helps support consistent sound control and performance during demanding riding conditions. Compared with a stock exhaust, this system is lighter, stronger, and designed to help deliver increased power throughout the motorcycle’s operating range.

The Powercore 4 S/A features a U.S. Forest Service-approved, maintenance-free stainless steel spark arrestor screen for off-road use where an approved spark arrestor is required. This FMF muffler and header assembly fits 2014, 2015, 2016, 2017, and 2018 Honda CRF125F models.
