This is the finest exhaust available for the Porsche 991 Carrera S and 4S available. Period. The AWE SwitchPath™ Exhaust for the Porsche 991 is for those looking to increase power and bring out the note of their 3.8L power plant, without turning their backs on perfect daily-drivability and Porsche sophistication. It's Track and Touring, all in one elegant SwitchPath™ Exhaust. Constructed from T304 Stainless Steel, the AWE Porsche 991 SwitchPath™ Exhaust shows midrange gains of 20hp and 25tq at the crank and weighs in at 7.5lbs less than the stock unit, accomplished by replacing the stock center muffler with AWE-engineered strategically sized straight pipe sections. 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 Porsche’s 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.
