FMF Powerbomb Head Pipe Steel Yamaha YZF/WRF 400/426FMF
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 mxtotal.com.
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).
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.
