Fabspeed Porsche 991 Carrera Center Muffler Bypass X-Pipe (Non-Valved Exhaust) (2012-2016)
The Fabspeed Porsche 991 Carrera Center Muffler Bypass X-Pipe replaces the factory center muffler with a high-flow X-pipe that pairs perfectly with stock side mufflers or Fabspeed Maxflo side exhaust. It delivers 16 whp and 14 ft-lbs peak gains plus power across the RPM range while cutting 12 lbs of weight for better performance. This direct bolt-on upgrade transforms exhaust sound into a louder more aggressive sports car note on 2012-2016 Porsche 991 Carrera models without factory valved exhaust.
