I really don't want this thing to be obnoxious. I want a good deep growl. If I do the DP and IC, I could go stage 2. however, I don't want some obnoxious racer.
Anyone done this and have a video? Hard to find info on YT.

Intercooler shouldn't change your exhaust note, at least not to my knowledge.
Catless downpipe will make your cold starts loud, but BM3 allows you to disable the startup roar if you don't like it or need it.
Here's a video of an F30 335i which has the same engine as our cars and with a catless DP and stock muffler:
It probably won't be a 1:1 replication for our specific cars but should give you a general idea. Remember videos don't do exhaust notes any justice. In person and on video are two entirely separate things.
See if you can source M Performance mufflers, they'll give you that deep growl that you're after.
