    The science behind the Megabomb header may be FMF's greatest engineering accomplishment to date. You can bolt on a Megabomb with an existing FMF Racing slip on for as much as a 3hp boost, plus the Megabomb actually reduces noises levels by as much as 1.5dB. The Megabomb technology is revolved to produce more low end to mid-range gains as well as broadening out the mid to top end power gains over stock. The Megabomb is best used for Motocross/Supercross and GNCC style trails. Used by Factory Teams, the Megabomb is the next level technology you can have today.
  • Produces long header torque and short header over-rev.
  • Reduces sound output as much as 1.5dB.
  • Increases output from stock motor as much as 3hp.
  • #1 Header in Supercross, Motocross, Motocross of Nations and Monster Energy Cup!

Great exhaust Kx250f
The megabomb was a great addition to the 4.1 muffler. I little deeper tone over stock and muffler. Added a little bottom end grunt and pull, and the whole system together really Gives the bike a better and smoother pull all the way through the power curve.

Great Quality and finish. Tuckes away close to the motor so it doesn't rub on my boots and pants.

Love FMF
Replaced my OEM header with this and immediately found increased power and my bike would start easier. The only item is the mega bomb increased size easily burns your pants to, i suggest that you use a heat shield.

Awesome header pipe. Installed on my 2003 WR450F and my 2014 WR450F. Gave both bikes extra bottom end grunt. Looks great too

Will this require the FMF silencer? or can I use my stock silencers?
Parker G on May 2, 2017
BEST ANSWER: Yes it should work but you won't really get the max benefit out of the header if any. The header was designed to work best with the fmf silencer. I would save up and purchase a silencer too
I have an 07 trx450er. Will this work with a Yoshimura silencer?
A shopper on May 3, 2017
BEST ANSWER: As long as the yoshimura is a slip on designed to work with the stock header than yes it will bolt right on no problem
does this include the mid pipe?
A shopper on Jan 1, 2017
BEST ANSWER: For my 2007 YZ250F, it was only the header. However, on my full FMF exhaust, I purchased this part to replace only the front header and I had everything I needed. Simply unbolt the existing headpiece and replace with this one. Personally, I ended up taking the full exhaust off and re-mounting everything just to make it fit all nice and neat. In terms of performance, this is my favorite header - much better than stock all around and I even prefer it everywhere (bottom and top end) compared to the FMF power bomb.
It says for closed competition only , but can you tell if you put it on and use for street use ?
darrell m on Aug 12, 2017
BEST ANSWER: In my application for a 2007 Yamaha YZ250F, the motorcycle is not street legal and therefore street use was not an issue. If you have a street legal motorcycle that will accept this part, it will probably make a noticeable power gain...but in terms of being legal for street use, that might depend upon specific laws in your area. On my bike, I used it for trail riding, mx track practice and occasional racing, so it was not only used in a competition setting.
Is this or the powerbomb better for motocross?
Hannah C on Feb 14, 2017
BEST ANSWER: I've ran both headers. I prefer the megabomb for mx because it gives a better hit off the bottom to mid range .
is this a bigger pipe than the yz450fx? size wise, like if the fx pipe is 2 inches will this be bigger than that or no???
A shopper on May 20, 2017
BEST ANSWER: FMF build their pipes to be OEM compatible. For instance, I just put the Mega Bomb header and connected it to my stock silencers. The only part of the header that is larger than OEM is the chamber.
