The Hex Q4 is no different. With a series of internal baffles, chambers, and sound-absorbing materials, FMF has created a silencer that accelerates exhaust flow while still keeping noise low. With FMF’s Hex Q4 S/A Silencer, you don’t have to choose between low sound and excellent power.

Super stoked to get exactly what I needed pretty quickly. My KTM is 11 years old so it is getting harder to get aftermarket parts for it!
