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 Q4 Hex Slip-On muffler, which replaces your heavy and restrictive stock muffler. It also includes an EJK 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. You can either use your stock header pipe with the Q4 muffler, or optionally add to the package one of FMF's header pipes... either the PowerBomb or MegaBomb header. Finally, you can also optionally add a 13 Tooth Front Sprocket.

Header Recommendations:
If you have a 2017+ CRF250L Rally, an aftermarket header pipe is not quite as necessary as on the 2013-2016 CRF250L 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 FMF Q4 muffler is our favorite for the CRF250L Rally thanks to its built in quiet technology. With riding areas threatened more every day, FMF takes seriously the expression "less sound equals more ground" and with the Q4, FMF has designed a slip-on exhaust that leads in high performance quiet technology. Using the best materials, the Q4 uses intricate chambers and baffles to improve flow while still dampening sound. Roost more, ride more and offend less with the FMF Q4!
