    We've been sellling performance parts for the 2017-2020 Honda CRF250L and Rally for several years now and have learned what our customers want in a performance exhaust package to improve the bikes performance and make it run better. With this Performance Exhaust Bundle, we've combined several of the most popular performance products for the 2017-2020 Honda CRF250L / Rally into a handy package deal. The package is based around the FMF Q4 Hex Slip-On muffler, which has been our best selling muffler for this bike over the years. You can also select the Yoshimura RS-4 Muffler as an option to the FMF Q4. Many customers choose to use their stock header pipe with the muffler, so this package does not include a header pipe and you will re-use your stock header. The package 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.

    Fitment: 2017-2020 Honda CRF250L / CRF250L Rally

    Sound: The FMF Q4 Muffler is the quietest aftermarket muffler available for the Honda CRF250L. It is still louder than stock, but quieter than other aftermarket mufflers. If you want a quiet exhaust on your CRF, this is the one. The Yoshimura RS-4 will be slightly louder.


    One (1) CRF250L FMF Q4 Hex Slip-On Muffler:
  • Constructed from aircraft grade aluminum and high strength stainless steel
  • Removable USFS spark arrestor included
  • Pounds lighter than stock
  • Twin stage core design for lower sound output and extended life of packing material
  • Includes mid pipe insert if you want to use with the smaller stock header pipe
  • Max Sound output 96dB; most models below 93dB
  • 2017-2020 CRF250L - Part #041568
  • 2017-2020 CRF250L Rally - Part #041570

    One (1) EFI Controller:
    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, which is very simple to install and plug into existing wiring using stock connectors. Details below.
