The science behind the MegaBomb header may be FMF's greatest engineering accomplishment to date. You can bolt on a MegaBomb for as much as a 3 horsepower boost, plus the MegaBomb actually reduces noise levels by as much as 1.5dB. The FMF MegaBomb header is yet another testament to the continued dedication of FMF to developing the best performing motorcycle exhaust components. Used by Factory Teams, the MegaBomb is the next level technology you can have today.

  • Produces long header torque and short header over-rev.
  • The larger midsection creates a larger surface area for sound dissipation to reduce the sound output by as much as 1.5dB.
  • Increases output from stock motor as much as 3 HP, alone.
  • Constructed out of FMF's exclusive Ti-Metal for an extreme weight savings with added durability.
  • Designed with a unique midsection, comparable to the Powerbomb header, that provides improved power across the power range.
  • The unique design of the MegaBomb header allows for better low end torque similar to a long header while also improving top end power much like a short header.
  • Although the MegaBomb header offers the advantages of a long header, the design of the MegaBomb header reduces the length and the chances of getting in the way or suffering damage.

Instant POWER

I gotta admit I was pretty excited to get my new fmf megabomb header and I was pretty upset when I found out the previous owner had switched the midpipe gasket out so my megabomb didn't fit not to worry though MotoSport.com sent a brand new gasket that fits free of charge
After that it only took 5 Minutes to bolt on and the power increase was so great it almost felt like my 1st time on a bike again.
Thanks Motosport.com you da bomb.

Looks great performs just as good

noticeable bolt on power and makes the bike look sweet. just put one on a 2012 yz250f and definitely felt more top end. would recommend rejetting your bike after installation.

Looks great fits great

Good power with correct jetting on my 08 trx450r. The pipe gets very hot but I'm just used to header wrap on my pipes. This thing is too cool to be covered up and turns puple after 2hrs.Not much over rev but plenty of low-mid torque

Great Header

I bought this header for my 2006 kx250f. It works great and the power is very noticable. The only problem I ran into was the installation. My kickstart lever was resting on the header when i pushed it in. I had to take it off and put it in a different position and then grind about 1/4 inch off the top of the lever. But besides that it is a great pipe.

Amazing

This product is amazing. I put it on my 2010 crf250r with a fmf q4, this is an amazing combo. It really Brought the bottom end up, and created alot more top end and over rev. Overall it is a great product.

Amazing exhaust header

This header is just everything you could ask for and more. It is simply the best money you can spend for a power increase on your bike. Besides its amazing looks, it WILL increase your low end power and torque by a very noticeable amount without sacrificing the mid and top end. Great overall pipe, makes your bike sound amazing too.

FMF headers, whether it be the PowerBomb or the MegaBomb, are fitted to match an FMF series muffler. We do not recommend or guarantee you try to match it to a stock muffler or other after market muffler.

Stainless steel to titanium?
I have a 2015 CRF250r and I switched to the FMF 4.1 single sided exhaust. I bought the aluminum slip on with stainless steel mid pipe. I’m curious if the titanium header will fit with the aluminum slip on with stainless steel mid pipe? Or will I have to get the stainless steel header?

I have a crf150r will I still need to jet it and what gasket would I need to get this thing to work?

Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there. The OEM gaskets can be found in our OEM section here:

09 yfz 450?
This is a 4 part question. Will this fit on my 09 yfz 450 with a slip on hmf pipe? Also will my stock heat shield fit on this, if not can I put exhaust heat wrap on it? Will I have to do anything with my efi controler? Finally what is the benifits of titanium over stainless steel?

Yes this FMF Megabomb Header will fit your 2009 Yamaha YFZ450. Just be sure to correctly select the Year/Make/Model of your ATV before ordering so we can be sure to send you the correct header for your ATV. FMF headers, whether it be the PowerBomb or the MegaBomb, are fitted to match an FMF series muffler. We do not recommend or guarantee you try to match it to a stock or other aftermarket muffler.. The FMF header is not compatible with the stock heat shield however you can use an exhaust heat wrap. For maximum performance programming would be recommended. The benefit of the titanium is the weight savings.
Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
