FMF PowerBomb Header:
- Stainless steel motorcycle 4-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 the flow increases nearly 10%
- The ducted core allows the exhaust gases to exit into the Bomb chamber, expand, cool and ramp back up at a higher velocity
- Acts as a 'pre-muffler' to lower the dirt bike's sound output by as much as 1.5dB through providing more sound absorbing surface area for the sound medium (exhaust gases)
- Proven PowerBomb patented technology provides increased performance of up to 10% horsepower gain
- Only available from FMF Racing, don't be fooled by knock-offs
- The most copied header in the world
