535i Catless Downpipe Rasp - Vibrant Resonators?

Installed my VRSF 3.5" catless downpipe this weekend and WOW, it sounds extremely mean and the turbo spool/noise is intoxicating.

That being said, there is a fair bit of rasp when cruising in D and when going WOT. I'm starting to think it's a bit much for a luxury sedan, and I don't want that type of negative attention.

My current setup is:
VRSF Downpipe
Resonator Delete w/ X Pipe
M5 Mufflers (valves closed)

Should I put the stock resonator back in? Should I instead go with Vibrant 1790 (2.25 inlet/outlet, 12in length) resonators instead of the stock?

Any input is greatly appreciated! Videos below, cause I know it will be asked for.
