You need an SDS drill ..with a core drill bit around 40mm...
Mark your point where the pipe will go through on the inside...drill through the block first, and them part way through the outer brick..until your guide drill breaks through.
You now need to get outside and drill back through the wall until the core drill breaks through.
Drilling back through from outside means that the face of the brick will be neatly cut and allow for an easy finish around the pipe exit hole.
