CRF450X'05-17 - FMF SS PowerBomb Header
Description
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).

Just installed one on my CRF450X and it fits great and when installed along with a Powercore 4 it gives a great note and feels as though it has added some more power

This along with a powercore slip on made a huge difference in both power and sound...compared to the Big Gun Evo X that I had been running, this thing is practically silent. Highly recommended...

An excellent addition to my Q-4 can. FMF high quality. Didnt quiet the bike so much, definetly helped low to mid range. Went with the carbon guard as well, trick and keeps those roost dings down. Saves your pants too!
