Porsche 991 GT3 Sharkwerks Muffler Bypass
A little video of the 2015 Porsche 991 GT3 with a newly installed Sharkwerks Muffler bypass. In sport mode, the car is significantly louder although valves interfere at low rpms (like stock). Light accelerations, as the car was still under 2k miles at the time.
