KAWASAKI KLX250S 2009

We have a variety of pre-configured systems to choose from, but not every option is sold as a system. If you want a little more flexibility, use this tool to build a system for your bike. You can choose a preconfigured system, or design your own by selecting both a header and a muffler.

Headers

  • MegaBomb

    MegaBomb

    $274.99
    (click for more info)
    • Item ID: 042251
    • Type: Header
    • Header Const: Stainless Steel
    • Header Type: MegaBomb
    • Fitment: use with stock or FMF muffler
    • Weight: 1.7 lbs.

    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 materials
  • PowerBomb

    PowerBomb

    $199.99
    (click for more info)
    • Item ID: 042155
    • Type: Header
    • Header Const: Stainless Steel
    • Header Type: PowerBomb
    • Fitment: use with stock or FMF muffler
    • Weight: 1.4 lbs.

    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.

    These Carbon Fiber heat shields are made to fit all FMF Titanium and Stainless Steel Megabomb Header systems. Use what the FMF Factory teams use!     This will not work on the Powerbomb header as the diameter is to large to cover the complete header.
