FMF 4 Stroke Header Pipes
FMF 4 Stroke Header Pipes
The science behind the Megabomb header may be our greatest engineering accomplishment to date. You can bolt on a Megabomb with an existing FMF Racing slip on for as much as a 3hp boost, plus the Megabomb actually reduces noises levels by as much as 1.5dB. The Megabomb technology is revolved to produce more low end to mid range gains as well as broadening out the mid to top end power gains over stock. The Megabomb is best used for Motocross/Supercross and GNCC style trails. Used by Factory Teams, the Megabomb is the next level technology you can have today.
- Produces long header torque and short header over-rev
- Reduces sound output as much as 1.5dB
- Increases output from stock motor as much as 3hp
- Made from premium American TiMetal material
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.
Products marked as "In Stock" are stored in our different distribution centers. These products will ship within 1-3 business days.
Items are then sent by courier, we use Courierpost & Posthaste which will take 1-3 days to arrive depending on your location and the size of the parcel.
While we will do our best to ship from the distribution center closest to you, not all items will always be in stock in every location at all times. In some cases we will split the order and ship each package out to you individually and in other cases we may need to consolidate the items in one location to ship out as one package.
