    The FMF Q4 Hex exhaust is our most popular slip-on muffler for the 2017+ Honda CRF250L Rally. The Q4 has always been in a league of its own and FMF's latest Q4 HEX is the most significant upgrade to date. You donít need to settle for a plugged up moto muffler hampered by an low noise insert when you can have a sound-compliant muffler engineered for performance. Run the Q4 Slip-On muffler with your stock header, or pair it with the FMF MegaBomb or Powerbomb header, to really wake up the engine on your bike, as well as give it a much better sound.

    With riding areas threatened more every day, FMF takes seriously the expression "less sound equals more ground" and with the Q4, FMF has designed a slip-on exhaust that leads in high performance quiet technology. Using the best materials, the Q4 uses intricate chambers and baffles to improve flow while still dampening sound. Roost more, ride more and offend less with the FMF Q4!
