Description Item #FMF0005

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.

Tricky install

Purchased for a 2016 350 sx-f and took a good deal to get it to fit right. But other than that great exhaust and nice power boost

Works better than expected

It's worth purchasing this header for the weight reduction alone, but 3 extra HP is noticeable.

Motosport was out of the header and pipe together--on backorder for 4 months! so I had to purchase separate at $50 more. Bummed about that!

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.

Not durable

looks and works well until it breaks. Just went through my second one in two years. Is not durable and will be trying a different exhaust for a Honda 450r.

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.

Great Add-on

To start off this pipe is expensive. I feel that i will get my money out of it. It performs amazing and adds tons of power with the Powercore 4. Ended up it runs perfect with my jetting so i left the jetting. I used it on a 2005 Honda CRF250R

ALSOME!!!

I bought this product for my 2007 crf250r, and i just put it on with my stock pipes. It adds alot of low it mid range power. It is the easiest way to add "simple" power!! took 5 min. to put on.

Poor construction

I would highly recommend going with the stainless version. Titanium pipe is NOT made to last very long. I had one and pipe broke at the weld and FMF will do nothing to fix a poor factory weld

Wow!!!!!! =)

This mega bomb was amazing i bought it cause my header pipe for my 2009 Kx450f cracked and bent. but this thing made my bike roar even more. its bottom end its so smooth and gives way more power even with out being programed you can just feel it :) also it gave awesome results all the way through the bottom to top end. it looks great and they all say that this will make your bike quieter. but all it did to mine was give it a lower humming sound it almost seems lowder haha so dont get ur panties in a bunch if u like ur bike loud this thing will blow u away. 6 outa 5 stars :) definatley worth your time and purchase. also heres some pictures to give you an idea of what it looks like, haha i hate it when ppl dont give picts when they right reviews. the first is before the second is after... also very easy instalment it will take about ten minutes cuz it doesnt like to fit very well with the gasket in the mid pipe but it will squeeze in just push hard hhaha

the awesome megabomb :)
before also if u look close you can see the twist up by the mount. the cracks are underneath i didnt discover them till after i took it off.

Added good low end

It added a lot of low end without sacrificing any on the top of my 08 KX 250F. It helps me get out of tight corners a little quicker as I weigh 207.

A: 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.

Q: Stainless steel to titanium?
Over 9 months ago
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?

A: 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:

Q: 09 yfz 450?
Over 10 months ago
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?

A: 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.
