Home > Dual Sport Parts > Honda CRF450L > FMF PowerCore 4 / MegaBomb Full Exhaust

We've combined several of the most popular FMF products for the new 2019+ Honda CRF450X into one simple exhaust package. The package consists of the FMF PowerCore 4 Hex Slip-On muffler and the FMF MegaBomb header pipe. This full exhaust system is slightly less restrictive than the FMF Q4 / FMF MegaBomb system, but it is also louder from a sound standpoint.
