FMF Q4 Hex Slip-On Muffler for Yamaha YZ250F 4-Stroke/YZ250FX 4-Stroke/WR250F

Product Details

The FMF Q has always been in a league of its own and the Q4 HEX is the most significant upgrade to date. Don't settle for a plugged-up moto muffler hampered by a power-robbing exhaust insert when you can have a compliant muffler that's engineered for performance. More power, with less noise in a nifty HEX-shaped muffler design. FMF 's Q4 HEX is proof that FMF is the only US manufacturer to offer dedicated quiet exhaust systems.
