On both 540C/570S standard exhaust is the same as is optional sport exhaust. Sport exhaust is louder in complete rev range but, basic tone is the same. It is more sporty and agressive tone then in 991.2 Turbo for example.

Standard tires are P Zero MC1 which are in lastes version similar to P Zero N1 for Porsche.

Official 0-200km/h is 10.5s for 540C. I can alread tell you that press example that SA got is faster. 540C is as fast in real world in 0-200km/h as 991.2 Turbo and faster in 0-250km/h and 0-300km/h. Since 570S got 27.3s for 0-300km/h in SA you can expect 28.5s-29.0s for 540C. Fast enough IMO, especially for 160K € base price in Germany.

Here is nice example in Storm Grey with optional Stealth finish forged wheels.
