    Inside Megabomb header

    I put a FMF Megabomb header on my 450x today. Seems like it just smoothed over the whole power curve. Feels like it took away some of the off-idle hit and put it further up.

    I took a pic of the inside and it looks like there's just a single ~1/2" hole in the chamber section? I guess it works...
