As the legend of the naturally aspirated GT3 lives on, it is our duty to ensure that these cars sing even more than factory. Welcome to the Valvetronic Designs Valved Sport Exhaust System for the 992 GT3 platform. With this new generation of GT3, the exhaust configuration changed dramatically from the earlier 997 and 991 cars.

This new configuration features electronic exhaust valves that utilize the factory exhaust valve motors, and our traditional large cross-section X pipe for that very fruity RSR sound.
