Wow. How does it sound? Does it improve the consumption or power?

Thank you guys !
With two 3" split pipes , 535d sounds like V8, you can hear the deep tone from both sides.
Not know about the power gain or not, rev quicker is one sure thing I observed.

Great looking exhause - very clean.
Any chance of a soundtrack? - I love the 535d sound when gunning it, must sound even better with a quad

Before take a sound clip,
I can always hear a little drone inside the cabin but not as loud as petrol with exhaust mod like Remus.
Guess only 1/3 of sound volume compared with petrol at same rpm.
Surprisingly the diesel is still quiet and make me wonder what muffler is for ?

I already done it. View my thread: LINK. I also have there sound clips.
Those pics is from a 535d? The original DPF has 2x outlet pipes.
I realized that you have a lci model. Maybe only the pre-lci has a DPF with one inlet pipe and two outlet pipes...
About the V8 sound you are right about that. 
For the DPF bypass, the only thing that i know that is possible, is to modify its interior to get free flow. With only a bypass you will get the cel light and going into limp mode. I'm more concerned about the catalytic that is placed in the exit of the turbo, than the dpf that is placed at the middle of the 535d exhaust system, because the catalytic is what retains the exhaust gases, overheat the turbos and let to the usual broken header gasket.
