The AWE SwitchPath Exhaust for the Porsche 991 is for those looking to increase power and bring out the note of their 3. 4L power plant, without turning their backs on perfect daily drivability and Porsche sophistication. The AWE Porsche 991 SwitchPath Exhaust includes integrated valves designed to afford drivers the best of both worlds: A Track Edition Exhaust and a Touring Edition Exhaust, all in one. The AWE Porsche 991 SwitchPath Exhaust responds to the exhaust valve position commands sent from your Porsches ECU dependent on your throttle input. This means that the AWE Porsche 991 SwitchPath Exhaust will transform from Track (The SwitchPath valve directs exhaust gasses away from the side mufflers, for Cup Car levels of announcement) to Touring (The SwitchPath valve closes, routing exhaust gasses through the stock side mufflers, for a sophisticated, signature AWE tone, at a volume slightly above stock). Exhaust volume change matches the driving style: Aggressive throttle input elicits aggressive exhaust volume; tame throttle input elicits tame exhaust volume. All PSE console button controls are completely retained. This system was developed first, on a PDK car. The exhaust was created to be 100% PDK friendly.

And better still, none of the components of our AWE Porsche 991 SwitchPath Exhaust affect or alter any of the emissions devices on the vehicle, and therefore this exhaust is fully legal for street use. This edition retains the factory Porsche tips, so you can keep that rear looking stealth. This is the exhaust You've been waiting for, only from AWE.
