    We've combined several of the most popular performance products for the 2017+ Honda CRF250L 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 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!

    Header Recommendations:
    If you have a 2017+ CRF250L or CRF250L Rally, an aftermarket header pipe is not quite as necessary as the 2013-2016 bikes 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 and CRF250L Rally project bikes. If you have a 2013-2016 CRF250L, we highly recommend adding one of the FMF headers to the package. The stock header on that bike is tiny and restricts flow. Many of our customers prefer the PowerBomb header because its Power Bulge is smaller and more tucked in than the Megabombs, plus it allows you to re-use your stock header heat shield. Here are the headers that FMF offers for the CRF250L...

  • Customer Comments:
    Just installed SRmoto’s FMF Q4 Performance Pack for my 2017 Honda CRF250L. The kit comes complete with everything needed to uncork this bike and let it reach its full power potential. The FMF power bomb header, together with the FMF Q4 muffler combined with EJK’s pre-programmed EFI controller is truly amazing! I can honestly say I wasn’t expecting these type of results from a tune and pipe! The installation process was effortless and seamless. The folks at SRmoto provided excellent service and were fantastic to work with! Many thanks to Brett (owner)! I would highly recommend this kit for anybody wanting to gain power and lose a little weight (Bonus!!) in the process.

  • Many CRF250L 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.
