    • Fabspeed offering valved 2017-2019 Porsche 911 (991.2) 3.0 PSE exhaust bypass system - Weight savings and torque gains

      Speaking from experience the factory PSE (Porsche Sport Exhaust) valved system for 2017-2019 Porsche 911 3.0 models is heavy and somewhat restrictive. Fortunately, Fabspeed has a solution that not only sheds pounds but unlocks power and sound.


      It still works with the factory PSE valve button:

      Peak horsepower only goes up by 2 horsepower at the wheels but you will notice a nice torque increase down low. Great gains from just a rear section.


      This is great way to improve on the PSE system.
