EGR Delete but Keeping the DPF (should i keep SCR)

[quandary]

Are there any opinion on the merits of this? I would like to keep the diesel exhaust smell to a minimum and am planning an ECU tune.

I don't see the value in removing the exhaust to add in a DOC catalytic. It's a lot of work and expense.

As long as the DPF regeneration is working, I can't see how soot would build in the intakes. So, I am thinking of keeping the DPF. It's almost no maintenance.

I am not sure if I should keep the SCR. I assume the diesel smell is burned off by SCR, so I think it should be kept in tact (but am asking the forum what they think). The only pain seems to be maintaining the DEF which is not really a pain at all.

If the SCR is disabled somehow in coding, can it stay in place? If there is a failure mode, what would it be? I assume the DEF would have to be burned off or drained to prevent crystallization.

I don't think creating additional thread will bring you more comments, ABC delete is not that popular in US due to the smog check regulations in many states.All the people who did it are here:

Were you able to find information you were looking for? I am looking for the exactly same set-up for quite some time and still have not found clear answer. if you did could you please share?

According to people that "can do" it for you, it would build up and kill your DPF faster (clog up).

RED_Y_ is right too. Plenty of forums on this. A quick search would have given you your answer.
