FMF 041586 Honda CRF450X Slip-On Muffler

FMF 041586 is a Powercore 4 Hex slip-on muffler designed to replace the original exhaust silencer and increase exhaust gas flow on Honda CRF450X four-stroke motorcycles. The computer-designed rear can and Hi-Flo end cap support improved exhaust evacuation, while the round perforated steel inner core directs exhaust through the muffler with reduced restriction. This component is intended for closed-course competition use only and should be installed with consideration for applicable noise and emissions requirements.

The assembly uses a stainless steel mid-pipe, an aluminum rear can, and perforated steel internal components. FMF's cross-weave internal packing manages sound dispersion through the muffler core. The elliptical canister shape provides a compact exhaust profile, while the slip-on configuration allows the replacement unit to mate with the existing header or designated mid-pipe connection. The package is designed around four-stroke exhaust flow characteristics and is suitable for riders seeking a competition-oriented replacement muffler for the specified motorcycle application.

The package includes the FMF Powercore 4 Hex rear muffler and the stainless steel mid-pipe required for the slip-on assembly. Fasteners, springs, brackets, or other installation hardware are included only when supplied by the manufacturer. Verify the year, make, and model before ordering because fitment data for a specific production year was not provided in the source listing.
