As the pioneer of quiet performance mufflers, FMF raised the bar again in 2007 with the second generation of Q series mufflers, the Q4.
Built from the ground up, the Q4 is a completely new design, engineered for maximum performance while maintaining a sound level at or near 93dB on most models. The Q4 is the market leader for low sound / high performance. Less sound equals more ground.
