FMF POWERBOMB HEADER S/S LTZ400 '03-09 / KFX400 '03-06 043209

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 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.

Features

About FMF

One man, in the name of power.

In 1973 Don Emler created FMF out of a desire to go faster. For nearly fifty years FMF has been leading in the pursuit of precision, power and speed.

1973 was about revolutionary firsts. Zeppelin, Floyd and the Stones were setting the world ablaze. We tasted our first Lite beer, rode our first Jet Ski, and Don Emler lit the torch sparking one of the most influential brands in motorcycle history. In his mind he is ALWAYS RACING.

Like most pioneering inventors, Big D built his performance exhausts with a sense of purpose. From day one…always striving for perfection. FMF is ALWAYS INNOVATING.

45 years later the song remains the same. FMF still engineers and builds everything by hand, from the ground up in the USA. As long as you dream of flying higher and going faster, we will continue to innovate and build things the right way…THE AMERICAN WAY.
