Description

If you’re running off-road, the FMF Q4 Muffler delivers genuine quiet power without the typical performance penalty that comes with most silencers. This muffler absorbs sound through precisely engineered baffles and chambers while maintaining the power delivery your engine produces, all while shaving unnecessary weight from your chassis. Built on decades of FMF’s championship racing heritage, the Q4 is engineered for riders and racers who refuse to compromise on either noise compliance or performance.
