Product Description
FMF PowerBomb Stainless Steel Header

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).

Andy Bountiful,  UT Good Product I got this a few weeks ago for my '06 crf 250x because I put a huge dent in the stock one. Initally I had a problem installing it (the stock pipe had sort of a metal gasket connecting to the stock muffler. I had to take that out) but I figured it out and it fits perfect. I haven't been on a hard core ride with it on yet but just when I started it up it sounded a ton better. I'm looking forward to seeing how it performs.

David Arndt Ann Arbor,  MI PowerBomb Header with Q4 Slip-On Exhaust on a WR250R I am very pleased with the low end power and rideability improvements adding these components have made. The stock setup was very jerky at low throttle. With the FMF upgrade including disabling the intake flapper valve, the bike can crawl through tight trails with little effort. On the high end, it rips the front wheel in 2nd gear now.

KC corona,  CA Bombs away Just what my CRF450X needed. Along with a Power Core 4 slip-on and jet kit my bike halls ass now. And the sound is more manly then stock. Also stainless steel is what I got it turn golden brown right away from the heat and looks great. A good buy in my eye.

Atom Aptos,  CA Good Head... This header was the perfect choice to pair with my FMF Q exhaust on my 2000 YZ426. It also was an excellent choice to get the header up and over the oil pump cover on this model (no more loosening the header when changing the oil filter. Good little boost in HP...

Doug Surrey,  BC Not bad at all! Super easy to install! Fit perfectly on my 2002 DRZ400E. Did not alter the sound of my FMF exhaust at all and gave me a tad more power. Plus it looks way better than the black/rusty looking stock header.

Lorin Smith Seattle ,  WA FMF Powerbomb Head pipe Bought this for my Suzuki DR-Z 400s. Well made and 5 ounces lighter than stock head pipe. Fits very nicely with no struggle. Location of the “powerbomb” places it very close to my carbon fiber engine case guards. High heat here may prove a problem over time. Noticeable increase in low end/mid range power, just as claimed. I like it!
