Everything I️ expected and more!

I️ bought this to add power and dampen the sound, and was amazing by the results. I️ have a 2004 yz250f and you can’t go wrong with the power of the mega bomb. This also has my bike set up with a full fmf exhaust which has been an excellent purchase.

2013 KX 250 F Megabomb

Decided to add the Megabomb header to my previously installed FMF silencer. Very light weight but not as solid as the OEM header. Installation was simple however joining to the FMF midpipe/silencer was difficult. Even with high temp grease, difficult to join together. I have never had this problem with FMF before. Likely just a "one-off" thing. I have already purchased a carbon heat shield to place over the header - you will burn your boots/pants if you are not careful.

Unable to detect a power increase but slightly more responsive throttle. The biggest change occurred when I installed the FMF silencer 6 months ago. It will give your bike that factory look.

A: The Megabomb will get you the bottom end you are wanting and has more power gains than the Powerbomb. Also have a larger expansion cavity will help reduce sound output as well.

A: We do not recommend mix and matching header pipes to exhausts. These items are very performance specific as well as machine fitment specific. There could be an issue with the ltr exhaust mounting brackits not lining up because of the taper of the pipe allowing it to slide on more or less then yoshimura intended.
