Just had our local customer Jeff swing by with his stunning 981 Boxster Spyder after he installed his Armytrix Exhaust. This exhaust is valvetronic and controllable via the Armytrix phone app or a wireless controller. If you are looking for a loud and aggressive exhaust with the option to close the valves for a more tame drive, this is the exhaust for you. Check out these beautiful pictures as well as some sound clips and a video from his personal youtube channel installing his system(be sure to throw him a sub!).
