Thanks to the BMW local dealer's help, this 535d got a perfect quad exhaust mod.
Here's the idea how I want the flow goes.
DPF/Cats => mid-silencer => Y split => (remove muffler) => quad tips

A plate to cover the hole from removed muffler.

50% to 50% exhaust flow distributed left and right, a perfect case.
