As if to make my frustration worse I drove a friends 996C4S yesterday with an unswitchable sports exhaust and the difference in sound to mine is quite pronounced.
It makes the car sound exactly as you would expect it to and begs the question why the PSE isn't standard fitment on the 997S - I could actually hear it over my own car with my windows up as we left a set of traffic light in an - ahem - spirited fashion!
If my OPC can't get a definitive delivery date soon, I may well switch back to the Tubistyle option?
As an aside, driving both cars back to back, very quickly on twisty A-roads, there really isn't much in it, the 997S showing it's modest power to weight advantage only at the upper reaches of the rev range. However, I'm not at all convinced about the handling advantage of the AWD system, certainly in the dry. Perhaps a similar wet weather comparison will reveal more. I shouldn't have to wait long - it is Easter bank holiday after all!
Otherwise, visual differences to the interior apart, it felt a very familiar place to be - and cost £16k less but only has 7k more miles on the clock, very nice car - doh!
