FMF is about moving forward, faster and the PowerCore 2.1 silencer is proof FMF remains committed to two stroke progression. This silencer takes the Yamaha YZ250 two stroke to the next level with improved throttle response and smooth, controllable power throughout the RPM range. The PowerCore 2.1 features a lightweight aluminum canister and end cap with a stainless-steel mid-pipe. A larger-diameter design allows for more packing material and longer packing life, while delivering a crisp, aggressive sound that two stroke riders expect. Made in the USA and pairs best with an FMF header pipe.
