  • Fitment

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. The 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 bike's sound output by providing more sound absorbing surface area for the sound medium (exhaust gases).

  • Tuned for bottom to mid performance.
  • PowerBomb headers are the front runner in performance headers.
  • Designed for full service access to oil filter.

FMF Powerbomb Header Pipe

This pipe is awesome. Replaced my stock pipe on my 07 KX 450f. As soon as I started the bike, on the stand, it seemed to run better and idle better, even on the stand! It had a better throttle response at the lowest rpm. Crisper than ever. Then I rode it, more power and quicker throttle response at the low to mid rpm's. And excellent power everywhere through the rpm range. Highly recommended. Get out and ride!

The power bomb header is a really good pipe it was super easy to install and really gave a nice look to the bike. The only issue i had with the s.s. pipe is the extreme discoloration went from stainless to gold to blue and yellow but other than that i really love this pipe!!!

This made a difference!

It's not very often you bolt something on your bike and feel the power difference right away. The FMF Powerbomb header did just that. The first time I started it I could hear a different sound even with the stock silencer. When I hit the track I could not believe the low to mid power hit.
I have a 2008 CRF450 that was already a great motor but this was worth every penny. Should have done it a long time ago.

Great for the money

Im 19 and on a budget so this with the powercore 4 slip on will add a ton of power all the way through the rpm range of your bike and if you have a yz250f it will give it quite a bit more top end also, that's what I have it on, but like I said if you wanna spend under 500 on a full system you'd be dumb to get anything else.

GREAT POWER !

The FMF Powerbomb added a nice little kick! I love the power boost in the low to mid range.. I would recommend this product to anyone looking for a new header or just some more power in general.. It sure did put a little more pep in my 2008 YZ450F!!

Perfect Fit

I installed this on an 06 CRF450X and fit perfect, sounds great and gave me the little boost that I was looking for. I matched it up with an old White Bros E2 slip on and it works great.

Really easy to mount up takes litterarly 10minutes. This + The FMF Powercore 4 muffler makes for a full exhaust system that sounds LOUD. (Almost to loud) I feel more power in low and mid but it can be improved even more if i buy a powercommander i believe.

Will this header fit my 2009 YFZ450?
I Bought this header for my 2005 Honda crf450r, but upgraded to the 2009 Honda, thus I have this never used header. However, my wife has the 2009 YFZ 450 atv, will this header fit it? Then I can just add a FMF slip on perhaps.
