Product Details

This FMF Racing Powercore 4 Hex Muffler is designed to give your Yamaha WR250F (2015-2019), YZ250F (2014-2018), or YZ250FX (2015-2019) a noticeable boost in power. You get the muffler itself, which is constructed from durable aluminum, along with stainless steel components for the Hi-Flo end caps. This combination offers a good balance of performance and strength, making it a solid option for riders looking for more usable power across all riding styles.

The muffler has been completely redesigned for late-model applications, aiming to increase horsepower and torque throughout the entire power band. It's a slip-on design, meaning it's intended to integrate with your existing exhaust system. A removable spark arrestor is included, which is important for trail riding to prevent wildfires.
