The engineers of Porsche AG, Stuttgart, have developed a new sports exhaust system for the latest generation of the 911, available as an option on new models as of February 2009. This special exhaust gives the customer the opportunity to adjust the 911’s unique sound to their personal preference; at the touch of a button, the exhaust system switches over to a more sporting and emotional sound.
The new sports exhaust system is made of modified stainless-steel main silencers and stands out through its two uniquely-styled dual tailpipes. The heart of the system is an exhaust flap on each main silencer activated by the engine’s electronic control system, which switches over to a more sporting sound. The system is activated by a separate button on the center 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$ and In Canada, the Manufacturer's Suggested Retail Price (MSRP) is $3,410. Starting in April 2009, Porsche will also offer a Tequipment version as a retrofit part.
