Question Panamera 4 2012 PSE resonator delete

A progress video of a Porsche Panamera 4 3.6L V6 (970) going from an extremely quiet exhaust tone to a super raspy one.

The initial setup was a stock exhaust with Sport tailpipes.

The next step was upgrading the system to a center console switch-operated Porsche Sport Exhaust (PSE), Porsche OEM Valvetronic system for a more lively and higher sound. Yet that seemed still quiet and didn't have the pops and crackles desired, so I Straight-piped my car by performing a Resonator delete (the only one in the PSE system). The only other restrictors are now the cats.

I like the outcome mainly due to the beautiful burbles/pops/crackles. However the tone/rasp is ugly and most comments I receive are that it doesn't suit a Porsche, so let me know if there are any solutions to that.
TL;DR: I straight piped my NA v6 Panamera 4 and now it's raspy, how can I fix it and keep the pops and crackles?

what would a cat-delete do to this setup?

Re-install the resonator to get rid of that rasp. For greater depth of sound delete the cats and keep the PSE and resonator. When deleting the cats without ECU calibration I suggest using 02 sensor extensions to assist with the CEL coming on.

any idea what result might I get if I delete the cats without putting back the resonator?

Increased sound level - but will still have RASP, maybe even more pronounced.
