The FMF Q has always been in a league of its own and our latest Q4 Hex is the finest example yet. A Patented core shape lowers sound levels while maintaining maximum power output, and the five-sided canister shape increases internal volume allowing for the use of more sound absorbing material. Roost more, ride more and offend less with the FMF Q4 Hex!
