anyone have a fmf megabomb header?

Recommended Posts

I've used the FMF megabomb and Q4 on 2 bikes, trying both bikes with the Q4, with and without the megabomb.  01 WR250F and 09 WR450F.  Neither bike came with a bulge in the header like the Powerbomb, as the later models do.  In both cases, if there is a power increase, it's small.  You would have to put the bike on a dyno to see it.  But it does make the bike noticeably quieter so I was more likely to use the power that was there.  So the megabomb makes a bike a little quieter with no restriction or loss of power.  Worth it to me as I don't want to bother other users of the areas where I ride.
