Q4

FMF is the leader in high performance quiet technology and the Q4 is the next evolution in off road exhaust. The Q4 employs intricate chambers, baffles and proprietary multistage packing material making it the best performing quiet muffler available. With the Q4 you don’t need to hear the power, just feel the power!

• Developed over years of championship off-road racing
• Max Sound output 96dB; most models below 93dB
• Constructed from aircraft grade aluminum and high strength stainless steel
• Use with stock or FMF header
• Removable spark arrestor included

The redesigned PowerBomb is a four-stroke header that incorporates FMF’s patented PowerBomb module at a precise location in the initial stage of the header. By positioning this “Bomb” at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust sonics through the system. Result is a flow increase of nearly 10%! The outer chamber in the Powerbomb allows the air to expand, cool and ramp back up at a higher velocity. Additionally, the PowerBomb is a “pre-muffler” of sorts which helps to lower the bikes sound output by providing more sound absorbing surface area for the sound medium (exhaust gases).
