Does anyone have the powerbomb header on a 400ex? How much did yoy pay? What gains have you noticed? I have the w/b e-series on my 400ex and heard the powerbomb header would work with it. Any response would be great.

 

It has not been released yet by FMF.. I have had mine on backorder from fmf for 4 months. I talked to fmf on friday and since I have had mine on backorder so long they are custom making me one. They are having issue with there mass producer of the pipe.
