FSA Omega MegaEXO Press fit BB 19mm removal (non standard BB86)
I contacted FSA and was told no tool exists for pressing/removing the 19mm BB. So I proceeded with the cave man approach:

I used a long 3/8" extension (female side against the BB bearing) and hammer to knock out the left side, it came out easy.

The right side was a challenge with the same setup (it would not budge) , I ended up punching the bearing out of the BB shell.

I got the rest of the shell out with a 22mm deep socket and a short 1/2" extension and the same hammer technique. I would advise using a large socket that fits as soon as you get one side of the BB out. 

The bearings/bb does not appear to be damaged and could be reused.
