Ferrari overtakes Bmw and makes Bmw rather unhappy. Legal move or not?

So i made an overtake on the bmw, pretty risky move and i slide a little bit on the exit so he hits me. On the next straight he pits me and takes both of us out. The guy in the bmw said it was my fault for making a "douchebag" move. Was my overtake legal or do i deserve a penalty?
