01-06 YZF250 P-BOMB SS PIPE, FMF 040073 POWERBOMB HEADER, FITS WRF 01-10

Yamaha WR250F WRF250 2007 - 2014

FMF: 040073

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 are achieved through the expansion and contraction of exhaust sonics through the system. 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 bike's 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 on the mid to upper RPM range.
