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. 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.
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!
2017+ Honda CRF250L Rally
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. Here are the headers that FMF offers for the CRF250L Rally...

OPTIONAL PARTS THAT CAN BE ADDED TO THE PACKAGE INCLUDE...
** 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 the EJK EFI Controller or JD Jetting EFI controller. Details below. Each are simple to install and plug into existing wiring using stock connectors.
Pre-programmed specifically for a Honda CRF250L
Simple install. Plugs into existing wiring using the stock connectors
Simple and easy tuning with no dyno required
Simple Push Button Adjustment Interface
Does not require a computer or software to tune
"On-the-fly' tuning. You can make fuel adjustments in your garage or on the side of the road
** OPTIONAL: 13T Front Sprocket (adds to package price):
Many CRF250L Rally owners swap out the stock front sprocket for a smaller 13T, so we've added it as an option for our FMF performance package. The sprocket is made from case hardened nickel chrome molybdenum steel. Choose the option below if you want us to include the sprocket as part of the package.
