FMF Powerbomb Header - Stainless Steel

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.
these headers only work with the fmf exhaust it will not fit on the stock pipe, found out the hard way.... 2012 crf250r
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!!!
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.
The Power bomb header came faster than expected in the mail, and it works/looks great on my CRF 450.
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.
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!!
I put this header on my KX450F with a FMF Q4 pipe and is a great combo; sounds and looks great.
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.
Great product easy install. Only wish it came with copper crush ring
Bought for sons Honda 150 was able to notice a difference with added power. Son was very pleased!
great header matched it up with my pc4 in ss. power builds very fast and revs out like it stats best of both worlds get long and short header power bans in one header.
I had my stock header crack, and with Motosport's excellent service I had this Powerbomb delivered within 2 days! Pretty smooth installment, and even a noticable power difference!
pay the extra $20 for the stock pipe. burns your leg and doesnt fit stock muffler. comes with a spacer because the tube is smaller in diameter and exhaust flow out the spacer. also the "power bomb" does nothing in performance. is the same diameter tube all the way through. power bomb is just to get you to buy it. get the stock pipe.
I got the fmf powerbomb header for my kx450. It took all of ten minutes to install. The power deliver seems to be smoother and you don't loose much on the top end. I would without a second thought buy another one. The only down fall with this header is it turned the ugliest bronze color I have ever seen within the first two rides. But that can be expected just wish it turned a little nicer and not so visible bronze. other then that what a great product and Motosport was fast and accurate with the delivery time. My next parts I will go through them instead of the other guys.
they r great i wish they made them stronger though i have bought 3 already and it cheaper than the mega bomb
i decided to go with the powercore 4 slip-on and purchase the powerbomb header separately, which made a full system, and was much cheaper than buying a full system. my 07 crf250r had huge gains righ out of the box with this exhaust, sounded and looked much better also. throw on a K&N filter and a FMF (DJ) jet kit and your bike will roar! the powerbomb gave much added power, and i dont think you'll get much more out of the megabomb, and the extra cost isn't worth it.
Made a huge difference in the bottom end for power. Didn't think I needed it, but it helps a great deal. anyone ordering the FMF muffler should purchase the header too.
