  Home > Dual Sport > Honda CRF250L Rally Parts > FMF PowerCore 4 Performance Package We've combined several of the most popular performance products for the 2017+ Honda CRF250L Rally into this handy package deal. The package is based around the FMF PowerCore 4 Hex Slip-On muffler, which replaces your heavy and restrictive stock muffler. You can either use your stock header pipe with the PC4 muffler, or optionally add to the package one of FMF's header... either the PowerBomb or MegaBomb. Additional options for the package include an EFI (electronic fuel injection) Controller, which is a plug-n-play device that will help take advantage of your new performance exhaust system and also make your bike run properly. Finally, you can also add a 13 Tooth Front Sprocket if you want to improve your bikes acceleration and low end response. Header Recommendations: If you have a 2017+ CRF250L or CRF250L Rally, an aftermarket header pipe is not quite as necessary as on the 2013-2016 models, because Honda spec'd the new bikes with a slightly larger exhaust to begin with, so your stock header pipe is sufficient. However, if you want to maximize performance, one of the FMF header pipes is probably better thanks to their Power Bulge technology. We are using the MegaBomb header on our CRF250L Rally project bike. Sound: The PowerCore 4 Slip-On Muffler included with this package is pretty loud. If you want an exhaust system that is a bit quieter, the FMF Q4 Performance Package is definitely the way to go. The Q4 Slip-On Muffler in that package is louder than stock, and sounds much better, without being excessively loud. Fitment: PACKAGE INCLUDES THE FOLLOWING... One (1) Honda CRF250L Rally FMF PowerCore 4 Hex Slip-On Muffler: OPTIONAL PARTS THAT CAN BE ADDED TO THE PACKAGE INCLUDE... ** OPTIONAL: Use stock header pipe, or add an FMF PowerBomb or MegaBomb Header (adds to package price): ** OPTIONAL: EFI Controller (adds to package price): An EFI (Electronic Fuel Injection) Controller is HIGHLY recommended any time you install an aftermarket exhaust and/or air filter on your fuel injected bike, otherwise you will see little to no performance gains, and the bike may even run poorly. At this time, we offer two different EFI options, the EJK EFI Controller and the JD Jetting EFI Controller. Details below. Each are simple to install and plug into existing wiring using stock connectors. ** OPTIONAL: 13T Front Sprocket (adds to package price): ** OUT OF STOCK - We no longer carry this item. Try the FMF Q4 Package. |
