Porsche 992 GT3 / GT3 RS Valved Performance Exhaust System - Yonristic Performance
Explore the Advanced Porsche 992 GT3 Valved Exhaust System
The Ultimate Symphony for Stuttgart’s Masterpiece
Our Porsche 992 GT3 / GT3 RS Valved Performance Exhaust System is built to unlock the true sound, response, and emotion of Porsche’s naturally aspirated flat-six. Designed around a 3-inch X-pipe architecture, 4-inch motorsport-style tips, precision TIG-welded construction, and both factory valve control and remote valve control capability, this system gives owners complete flexibility between OEM-style integration and full manual sound control. Fully bolt-on, reversible, CNC-machined, and available in AISI 304 stainless steel or Ti-6AL-4V titanium, this is the ultimate exhaust upgrade for GT3 and GT3 RS owners who want sharper response, reduced weight, and a true F1-inspired sound profile.
The Yonristic Performance Valved Exhaust System for the Porsche 992 GT3 / GT3 RS is engineered for drivers who want more than just volume. This system is designed to refine the entire sound character of the GT3 platform, bringing out the high-pitched, motorsport-inspired tone that the 4.0L naturally aspirated flat-six is capable of producing. Every section is designed as a fully bolt-on and reversible upgrade, requiring no cutting, welding, or permanent modification, so the integrity of your GT3 remains protected while the driving experience becomes dramatically more engaging.
At the center of the system is a 3-inch X-pipe architecture, selected for its ability to balance exhaust pulses, improve flow behavior, and create a more harmonized high-frequency sound. The X-pipe design helps the exhaust note build smoothly through the rev range, delivering a refined tone at low RPM and a sharp, exotic wail at wide-open throttle. Instead of producing a rough or uncontrolled sound, the system shapes the GT3’s voice into something cleaner, more precise, and more emotional.
The system is available in both AISI 304 stainless steel and Ti-6AL-4V titanium. Stainless steel provides long-term durability, corrosion resistance, and a strong, stable tone, while titanium offers major weight savings and a sharper, more resonant acoustic character. Both material options are hand TIG-welded for strength, consistency, and a premium visual finish.
A key update to this package is the dual valve-control flexibility. The system includes both factory valve control compatibility and remote valve control capability, giving owners the freedom to choose the setup that best fits their build. If you prefer OEM-style operation, the exhaust can be installed using factory valve control so the vehicle manages valve behavior through its original system. If you prefer full manual control, the included remote valve control allows you to open or close the valves on demand for maximum sound flexibility.
For customers choosing the remote valve control setup, we also include a valve simulator / valve eliminator in the package. This is designed to prevent valve-related warning lights or limp mode when the factory valve control is not being used. The goal is to give you the freedom of remote valve operation while keeping the vehicle’s electronic system satisfied when properly installed.
Developed from precise OEM scan data, every flange, bracket, and mounting point is engineered for factory-level fitment. CNC-machined connection points ensure accurate alignment, while reinforced mounting areas provide durability for both street and track use. From the 4-inch motorsport-style tips to the carefully finished welds, every detail is built to match the standard expected from a Porsche GT product.
This is not just an exhaust system. It is a complete sound, flow, and control upgrade for the 992 GT3 and GT3 RS.

Headers & Configuration Options
This system is available in multiple configurations depending on your sound and performance goals. Customers may choose the catback system only, or pair the catback with long-tube or MaxFlow collector header options for a more complete performance package.
Available Configurations:
Catback System
Catback + Free Flow Race Headers — MaxFlow Collector
Catback + 200-Cell Street Headers — MaxFlow Collector
The catback system is the ideal choice for owners looking to improve sound, reduce weight, and maintain a clean bolt-on setup. The header packages take the system further by increasing flow, sharpening throttle response, and intensifying the high-RPM sound character of the GT3 platform.

The Architecture of Sound
At the heart of the system is the 3-inch X-pipe design, a layout chosen specifically for the GT3 platform because of its ability to balance flow, smooth exhaust pulse interaction, and produce a cleaner high-frequency tone. The X-pipe allows both banks of the flat-six to interact in a controlled way, helping the sound climb naturally as RPM rises.
With the valves closed, the system maintains a refined and controlled tone for street driving, cold starts, and lower-speed use. With the valves open, the system unlocks the full character of the GT3’s naturally aspirated engine, producing a sharp, metallic, F1-inspired scream that becomes more intense as the engine approaches redline.
Dual Valve Control System
This exhaust system is designed to give owners full flexibility during installation. It supports both factory valve control and remote valve control, allowing you to choose the valve setup that best matches your driving style.
Factory valve control allows the exhaust to integrate with the vehicle’s original valve behavior, maintaining an OEM-style experience through Porsche’s factory logic. Remote valve control gives you manual command over the exhaust valves, allowing you to open or close them on demand without relying on factory programming.
If you choose to use the remote valve control setup, the package includes a valve simulator / valve eliminator to help prevent valve-related check engine lights or limp mode when the factory valve actuators are not being used. This makes the system more complete and gives customers confidence when choosing the remote-control option.
Uncompromising Craftsmanship
Every Yonristic Porsche 992 GT3 / GT3 RS exhaust is built with a focus on precision, durability, and visual detail. The system is available in Ti-6AL-4V titanium for maximum weight reduction and sharper resonance, or AISI 304 stainless steel for durability and long-term corrosion resistance. Titanium gives the exhaust a more responsive, motorsport-style sound character, while stainless steel provides a strong and refined tone with excellent daily-use durability.
Each joint is hand TIG-welded by skilled fabricators, with weld quality designed to deliver both structural reliability and a premium appearance. Internal flow paths are engineered to reduce turbulence, connection points are CNC-machined for alignment, and every mounting location is reinforced for track-level confidence.
The result is a system that looks as serious as it sounds.
