** OUT OF STOCK - This product is no longer in stock at our warehouse.
As of spring 2024, FMF has discontinued their mufflers and header pipes for the 2008-2020 Yamaha WR250R/X. Yoshimura is about the last company making an exhaust system for the Yamaha WR250R. See our Yamaha WR250R Performance Guide for all the details on what you need to get your WR250R/X running properly and increase power, torque and overall ride-ability.
The FMF PowerCore 4 Hex slip-on is one of the most affordable mufflers available for the Yamaha WR250R and WR250X. Run the PowerCore 4 Slip-On muffler with your stock header, or pair it with the FMF Powerbomb or MegaBomb header, to really wake up the engine on your bike, as well as give it a much better sound.
SOUND: Please note that the PowerCore 4 muffler is slightly louder than FMF's Q4 muffler. If you are looking for something quieter, check out the FMF Q4 Slip-On Muffler.
Fitment: 2008-2020 Yamaha WR250R / WR250X
