I'm a fan of the sports sound, as and when the mood takes. I had a GTS on loan which was a nicer sound..... good luck with the venture and I would be interested
My Turbo has the Porsche sound effect. It's anti-climactic. What I really would love to have is the Dodge Charger electric pseudo engine/exhaust sound. They did it the way I wish Porsche did. Accurate, menacing and linked to the throttle. All that is missing is a torsional twist of the body when goosing the throttle.
