    FMF Megabomb SS Header for WR250R/X 08-14

    NOTE: Works only with FMF Mufflers

    Derived from PowerBomb technology, the MegaBomb represents the natural evolution of performance -- improve on it, make it better. What started as a PowerBomb just kept growing. Simply put, the bigger it got, the better it worked. The engineering wasn't that simple, they had to fine tune the internal characteristics and there was an upper limit to what was feasible for performance as well as function, but through arduous testing, here you have it! The very same header you’ve seen on the Factory KTM and Yamaha of Troy bikes as well as Team Suzuki Off-Road and that of Ryan Hughes. This is not ‘Un-obtainium’. The MegaBomb™ ships right out of our warehouse to you just as it would to any race team!

    What makes a MegaBomb so different? There are two key aspects. First, the more exhaust gases that are extracted, the better. Like the difference between a garden hose and a fire hose -- except, too much is not good. The calculated size of the MegaBomb chamber, with the precise location and size of internal ducts, makes for increased volume. The second aspect is the performance difference between a short header, better over-rev, and a long header, better low-end torque. With the MegaBomb, you get the best of both. The added volume acts like a long header and the length has not been increased.


    • Works well with sound restricting mufflers
    • Reduces sound output by as much as 1.5dB
    • Less susceptible to damage than a long header
    • Produces low end of a long header and top end of a short header
    • Improved bottom to mid-range power
    • Exclusive high strength stainless steel construction
    • Actual pipe may vary from photo.
