Improves exhaust tone and saves weight by replacing the factory center muffler with a lightweight x-pipe. The 991 Carrera Valvetronic Center Muffler Bypass X-Pipe makes a great compliment to either the factory PSE side mufflers or to Fabspeed's Maxflo Performance Side Exhaust System. With valves open and closed you'll experience greater volume and a smoother tone than the factory Porsche exhaust system.
