CB and DP may add up to boost spike. The MP will cause boost creep. Both can blow your engine if you don't add fuel or keep your boost under control. Do a search, there's lots of info about these mods.

If he gets boost creep from the midpipe, I don't think a BC will help. Either port the waste-gate or leave the cat in place.

Yes, that should be fine.
