As you probably already know, Porsche builds some of the best sports cars in the world. The Porsche 911, specifically, is one of the most iconic cars of all time. Near the top of the 911 hierarchy, the GT3 and GT3RS offer performance to take on some of the best supercars in the world.
Porsche worked hard to give the GT3 and GT3RS insane levels of performance, but it still had to be a comfortable road car. This need for comfort forced Porsche to use very quiet exhaust systems on the GT3 and GT3RS.
As enthusiasts, we all want our cars to sound as awesome as they look. Luckily for 991 GT3 owners, there are lots of awesome options for aftermarket exhaust systems. This 991 GT3 came to the Vivid Racing shop for a VR Tuned ECU flash and an Armytrix Valvetronic exhaust.
Why Choose Armytrix?
What makes the Armytrix exhaust unique, is the Valvetronic system. The Valvetronic system allows you to switch between being quiet and being loud with the push of a button via the included remote or through the smartphone application; this works by tapping into a vacuum source on your engine and connecting it to the control module.
This OBDII module tells the exhaust valve module to allow the engine vacuum to open or close the exhaust valve. You can also set the exhaust valve module to an automatic mode which will open/close the exhaust valve based on predetermined RPM range or throttle position. For the 991 GT3, this means you can keep your car quiet in the neighborhood, but open the valves and let it scream on the open road!
The Result
After installation, we took this 991 GT3 out on the road to test the exhaust. Thanks to the Valvetronic feature, we could keep the GT3 quiet in town, but once we got out to the open road, we let it sing. We left the catalytic converters in place, since this is a road car and needs to abide with the law. Check out the full video below!
