The new sports exhaust system is made of modified stainless-steel main silencers and stands out clearly through its two dual tailpipes in unique design. The heart of the system is the exhaust flap on each main silencer activated by the engine's electronic control system and switching over to a more sporting sound as soon as the driver activates the sound mode. The system itself is activated by a separate button in the centre console varying the sound of the exhaust as a function of engine load, road speed and engine speed.
The Euro base price of the sports exhaust system is 1,610 Euro excluding taxes. In the US the Manufacturer's Suggested Retail Price (MSRP) is 2,500 US$. Starting in April 2009, Porsche will also be offering a Tequipment version for retrofitting.New Porsche 911 Turbo debuts at IAA
