Armytrix Car Exhausts for Porsche 991 (911) GT3 3.8L (2013-)

The 991 GT3 comes straight from track experience: a high-revving naturally aspirated 3.8 flat six with 475 PS, active rear-wheel steering, and it is the first GT3 offered with an automatic gearbox, the PDK dual-clutch.

For the Porsche 991 (911) GT3 3.8L (2013-) you will find a cat-back system by Armytrix, with Valvetronic silencers with remotely controlled valves and titanium components. It has twin outlets of 101 mm with blue titanium tips.

Armytrix systems are made in Taiwan in T304 stainless steel and titanium. At their heart is the valve in the silencer, opened and closed on command from the remote or the app, with a module that plugs into the car's OBD port.
