Engineered to elevate the sound and performance character of the Porsche 992 GT3 platform, the STRATEC Valved Sport Exhaust System (T304 Stainless Steel) delivers a sharp, high-revving motorsport tone designed to match the intensity of Porsche’s naturally aspirated flat-six.

Fully redesigned to accommodate the 992-generation exhaust layout, this system features a large cross-section X-pipe and electronic exhaust valves that retain factory valve motors, ensuring seamless integration and factory-style functionality.

With valves open, the exhaust produces a raw, aggressive, track-focused tone that enhances engagement through the upper RPM range. With valves closed, volume is reduced for a refined driving experience with minimal drone, making it suitable for daily use while still delivering thrilling performance when desired.
