FMF Racing PowerBomb Stainless Steel Header

• 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
• A “pre-muffler” of sorts which helps to lower the bike's sound output by providing more sound absorbing surface area for the sound medium (exhaust gases)
