The Factory Fatty is reminiscent of the 'works' or cone pipe once used by Factory Teams. It shares many of the same characteristics with its craftsmanship and material quality. The Factory Fatty broadens and smooths out the power curve while boosting gains throughout the entire power band, more low-end, more mid, and increased over-rev. No matter what type of riding you do, the Fatty has the benefits you're looking for.

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. 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...

The FMF Power Bomb is a four stroke header pipe unit that has a unique bulge precisely located in the header system A "pre muffler" of sorts, the Power Bomb actually lowers sound output because it creates more surface area to absorb the sound medium (exhaust) The surface area of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up with the higher pressure air The result? The FMF Power Bomb is instrumental in reducting the decibel level on any four stroke and because of the expansion and contraction on...
