Two Different Performance and Sound Paths
We offer two distinct exhaust systems for the Porsche 992 GT3 / RS—each designed with a different driving intent in mind.
The Standard Version (OEM Compatible Version) is built around flexibility. With valvetronic technology, exhaust gases can be routed through the muffler for a quieter, more refined drive—or opened up for a sharper, more aggressive tone when needed.
The Race Version takes a different approach. It’s designed with performance as the priority, delivering a consistently raw, high-pitched, motorsport-inspired sound. There’s no filtering of character—just a direct connection between engine and driver.
The Standard Version enhances the overall driving experience in a progressive way. With improved exhaust flow and reduced restriction compared to stock, it sharpens throttle response and adds a more engaging tone, while maintaining the flexibility and comfort expected from a daily-driven setup.
The Race Version, however, is engineered with a different objective—maximizing output by restoring the engine’s ability to breathe freely. Through a full high-flow system design, it delivers dyno-proven gains of up to +25 wheel horsepower (WHP) without ECU tuning. And with ECU tuning performance can be pushed even further.
As the revs climb past approximately 4,000 RPM, where the factory system typically begins to restrict flow, the Race Version continues to pull with greater urgency, delivering a more linear and sustained acceleration all the way to redline.
The result isn’t just more power on paper—it’s a sharper, more responsive driving experience, where every throttle input feels more immediate and the engine maintains its intensity throughout the entire rev range.
Control When You Want It
While the Race Version is built around maximum output, the Standard Version takes a more versatile approach—centering the experience around control.
At the core of this system is valvetronic technology, which allows the driver to actively manage exhaust flow and sound depending on the situation. With the valves closed, exhaust gases are routed through the muffler, resulting in a more refined and subdued tone suited for daily driving. Open the valves, and the system transforms—delivering a sharper, more aggressive exhaust note that brings out the character of the GT3 RS.
This dual-path design gives the Standard Version a distinct advantage in everyday usability. Whether navigating city streets, cruising on the highway, or opening up on a back road, the exhaust adapts to the moment—something a fixed, race-oriented system is not designed to do.
Beyond sound, valvetronic control also allows for a more flexible upgrade path. As a modular system, the Standard Version can be configured with different components over time—making it ideal for owners who want to gradually enhance performance without committing to a full race setup from the start.
