No matter if your racing or just riding around this exhaust helps with the bottom end power definitely worth the purchase!

This is the best upgrade to your bike!

This gave my bike so much more horsepower. Now I can pull wheelies anytime with instant throttle response compared the stock pipe. I recommend this pipe as one of the first mods you do to your bike and is well worth the money.

Super clean look and fast shipping

This thing is off the charts good, for the full system... this with the 4.1RCT silencer is the best in the market hands down.

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.

Question asked by Coleman

Question: I’ve got a 2016 crf450r, if I install the mega bomb header, will it need tuned up to run right and to get the most power out of it, or is it just a slip on and go kinda thing?

Answer: That is tough to say as we would need to know what muffler you are using

Question asked by Xenon

Question: So if I purchase a mega bomb header for my 04 YFZ 450 I can buy any FMF slip on, that has “exact fit” for my bike and it will connect perfectly to the header?

Answer: That is correct. The inlet and outlet of FMF headers are stock specs.

Question answered 4 months 16 days ago
Answer: The FMF Megabomb Header is a "pipe". You can mount a muffler on the header-pipe.
To help us to find parts to fit correctly and provide you with accurate information, we will need to know the year, make, and model of your motorcycle.

Question asked by Bubs

Question: What’s the recommendation for jetting with this header installed on a 2007 yfz450. Recently purchased it from a friend who never rode it and it glows red hot after a few minutes of just idling

Question answered Over 10 months ago
Answer: We unfortunately cannot give jetting recommendations due to the unknown factors such as fuel being used and elevation you are at. I would suggest giving your local shop to see if they have any recommendations or JD jetting may have some advice. JD jetting can be reached at 360-350-0557

Question: Would this work on my 2018 crf450r that I have a fmf single slip on

Answer: The FMF Megabomb Header - Titanium for the 2017-2018 CRF450R has two muffler outlets. The original exhaust system from Honda had two mufflers.

To find a muffler to fit your single header pipe, we will need to know the FMF part number on your header pipe.

Answer: The Megabomb and Q4 will pair great together giving you a nice strong torque curve while adding to the mid and top end range also.
