I've not heard them side by each but I had a 2020 with the "regular exhaust tips" and now own a 2023 with the black tips. Both with the same OEM performance exhaust system. They sound the same to me although my across the street neighbour thinks my 2023 sounds louder, with a cold start. He's not complaining: he actually likes the sound, since he's a "car person" although he's not into Corvettes.
But having said that, I'm still in the "break-in period" so I'm not hearing my exhaust note with high RPM's. Maybe (I doubt it) there will be a difference but the "start-up bark" sounds the same to me.
I'm interested to see your other responses.
