Normally I'd gently angle ground round a brick to remove it, how can I get the job done in this case? The downpipe is cast iron and can't be left disconected.

You have a serious problem there.
What you need is "stitching bars"
You chisel out the pointing and glue/cement the stitching bars in across the crack.
You can get behind the pipe with a seaming chisel no problem.
You can get hand chisels or SDS chisels.
