My ordered 997S will have the Sport Exhaust from factory (April build), Porsche accepted the option when the dealer processed the order last week and double-checked with Porsche Iberica and is confirmed available, at least for some of the orders until they can cope with great demand.

But likely for retrofit it will be only available after April the earliest, like RC says, since they will serve first factory cars and then start when demand is starting to be met on factory order will start to adress retrofic orders.

I really hope the exhaust's switch won't be operated by the sport button on the sport chrono cars since one thing has nothing to do with the other and there is no sense at all in mixing them!
Also the deactivation after 50km/h again? what do I buy the sport exhaust for, to hear it only 5% of the time? simply moronic, thats gotta go...
