FMF - Titanium Powerbomb Header
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
surface area of the perforated core lets the exhaust gasses exit into the "Bomb"
chamber and then 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). On some models, you can choose between a moto or
supercross version. The supercross version is designed for more low to mid-range
power where the moto version is focused in the mid to upper RPM range.
