Details

    The FMF Titanium Megabomb Header Pipe uses its unique midsection profile to deliver absolutely massive low-end power with additional gains across the remainder of your power band. The Megabomb does this by creating a large surface area for exhaust expansion and sound dissipation. What this means for you is 1.5 decibels of sound reduction so you can use your new power on any track or trail you want. You can get even more sound dampening too since the Megabomb works great with sound restricting mufflers. Best of all, these benefits comes in a great looking and strong titanium construction that is lighter than almost any other header pipe out there.

    Specs:
  • Works well with sound restricting mufflers
  • Effectively reduces sound output by as much as 1.5db
  • Less susceptible to damage than longer headers
  • Produces the low end power of longer headers with top end power of shorter headers
  • Large gains in bottom and mid-range power
  • Titanium metal construction greatly reduces weight and improves durability

Fmf megabomb titanium header
I purchased this header about one week ago and so far I am very impressed with the results I have seen. I have a 2015 kx250f and it produces very good bottom end power. If you are looking for a new header this fmf megabomb is the way to go. The only thing I had to purchase in addition to the header was the fmf exhaust spring kit which was not included with the header.

Specifically for the KTM/Husqvarnas..
This header is shorter than the factory KTM/Husky header, and best of all, its a two piece design. This means that, when you need to pull the shock, you don't have to pull the header off, just the muffler and mid pipe.

I installed the full system, including this header, on my FX450 and it made the biggest difference a 4 stroke aftermarket exhaust has ever made in my experience. The factory Husky exhaust is super restrictive.

MUST HAVE....FMF is the way to go
I made sure to call FMF before I purchase this item to see if my bike would need a tune. The mega bomb header will help at lower end RPMs and looks cool after it gets heated up a few times. I also ordered the all titanium FMF 4.1 silencer for my 2017 kx450f and it looks and sounds great. No issues with backfire anymore and it was just a bolt and go right out of the box.
Fast delivery

Love this pipe!
I bought this pipe for my 2008 CRF 450 R and absolutely love it. There is an obvious performance gain in the low and mid end power. I let my buddy ride my bike after I installed it and he bought one immediately after. Also this pipe looks awesome! 5/5 would definitely recommend this pipe.

Eye candy exhaust
Looks super awesome, perfect and easy install. Slight increase in horsepower, but not much. Especially for as expensive as they are, I expected a bigger horsepower and performance gain. Fortunately Rocky Mountain sells them at a discounted price!

Low/Mid Increase For Sure
Ran the Megabomb header on my YZ250F for a few seasons, when jetted correctly it boosted the low/mid power as expected and actually quieted the bike down. No issues with fitment and I actually used the stock muffler on my bike, the header has held up great even after some high speed falls with zero dents or damage.

For a 2017 Husqvarna FC450, after installing this header does the mapping need reprogrammed?
Ronald A on Sep 25, 2017
BEST ANSWER: I put it on my KTM 500 XC-W and it runs amazing. I even ride from 7000ft to over 10,000ft and nothing changed. Lovin’ efi!
Will this work with any slip on mufflers?
A shopper on Aug 8, 2017
BEST ANSWER: It will work with the stock slip on, so it should work with any muffler designed to replace the stock one.
do i need a mid pipe or it is dyrectly to the muffler ?
mike m on Apr 28, 2017
BEST ANSWER: It should work the stock muffler has the mid pipe attached to it but i don't know if the header will silp on the fmf header i have the whole system
I have a yfz450r that has a hmf competition series slip-on, will the fmf megabomb fit with my exhaust?
A shopper on Jan 4, 2018
BEST ANSWER: Yes, they were designed to fit together, and designed to provide optimum performance when used as a set.
will this go with a stock exhaust on a 2017 wr450f?
eric k on Apr 26, 2017
BEST ANSWER: I'm not sure if it will go with a stock exhaust. I purchased entire kit and silencer for a yz450f. Best purchase and better overall performance.
