Fabspeed Valvetronic X-Pipe Center Muffler Exhaust for 991 Porsche 911 Carrera / GTS / S

Fabspeed Valvetronic X-Pipe Center Muffler Exhaust for 991 Porsche 911 Carrera / GTS / S

Enhance the exhaust note, boost power, and reduce weight in the 991 Carrera by installing a Valvetronic Center Muffler Bypass X-Pipe. This Valvetronic exhaust system retains the functionality of the stock valved system, and if your vehicle lacks a driver-controlled valved system, you can introduce this feature using our valve controller. Simply choose “Standard Exhaust” from the dropdown menu. This exhaust system perfectly complements either the factory valved side mufflers or Fabspeed’s Maxflo Performance Side Exhaust System.
