Soul Performance Catted Valved Exhaust System for Porsche 911 (992.1 / 992.2) GT3 / GT3 RS 2021+
Upgrade your Porsche 992 GT3 or GT3 RS with the Soul Performance Catted Valved Exhaust System and give the car the edge it deserves. This system transforms the driving experience from the first startup to wide open throttle. Long tube runners and precision CNC merge collectors improve exhaust flow from the headers into a purpose built X-chamber muffler when the valves are closed. Open the valves and gases move through a large diameter X-pipe designed for maximum output and an elevated pitch. The result is a more exotic tone that climbs with urgency as the RPM increases. You always stay in control. Cruise quietly when you want. Let it rip when the road opens up. Volume responds directly to your right foot, so you decide how aggressive the car sounds in every moment.
Engineered for the Porsche 992 GT3 and 992 GT3 RS, this catted valved exhaust system delivers measurable flow gains, a refined yet intense soundtrack, and the kind of response you feel in the seat. If you want your GT3 or GT3 RS to sound as serious as it looks, this is the upgrade that brings it together.
Headers:
If you want measurable performance gains from your Porsche 911 GT3 or GT3 RS, a full catted valved exhaust system is one of the most effective upgrades you can make. This system allows the engine to breathe the way it was engineered to. The result is improved throttle response, increased horsepower, and a deeper, more aggressive exhaust note that matches the character of the car. The factory exhaust includes restrictive OEM catalytic converters and a large 7 5/8” connection to the rear muffler. Replacing these components with 200cell high-flow catalytic converters and a properly designed valved system improves exhaust flow and reduces back pressure. That means more usable power throughout the RPM range, whether you drive your GT3 on the street or at the track.
Rear Exhaust Section:
Soul Performance engineered this exhaust system to solve a tight packaging challenge under the vehicle while protecting performance. To keep the catalytic converters positioned correctly after the headers, the exhaust routing was carefully looped to maintain optimal exhaust velocity and consistent flow. Every bend and junction was designed with purpose to support power delivery and long-term reliability. Controlling cabin drone below 3,000 RPM was a key priority. After extensive testing, a purpose-built muffler delivered the best results. It reduces low RPM resonance inside the cabin while maintaining an aggressive touring sound outside the car. You get a refined driving experience during cruising speeds and a more engaging tone when you step on the throttle.
With the exhaust valves open, gases move freely through full 3” piping and a precision engineered X-pipe. This design merges both exhaust banks to improve scavenging and produce a higher pitched, refined exhaust note with maximum flow efficiency. The result is a responsive system that supports performance upgrades and spirited driving. When the valves are closed, exhaust gases are redirected through a secondary flow path and routed into Soul Performance’s straight through muffler. The internal construction uses perforated tubing wrapped in acoustic packing material. This setup allows gases to expand and dissipate sound energy without creating significant restriction. An integrated internal X-pipe further balances the flow between banks for smoother sound output.
These engineering details work together to minimize drone under 3,000 RPM while delivering the performance exhaust tone Porsche owners expect. Whether cruising on the highway or accelerating through the gears, this valved exhaust system provides controlled sound, efficient flow, and proven results for your Porsche performance build.
Valve Control:
This vehicle features electronically controlled exhaust valves with integrated actuators mounted to a free moving mechanical valve assembly. From the factory, the exhaust valve programming keeps the valves closed until approximately 4k RPM. Between 4k and 5k RPM, the valves progressively open. After 5k RPM, they remain fully open to allow maximum exhaust flow. If you want complete exhaust valve control, ECU tuning is available to override the factory programming. With proper calibration, the valves can remain 100 percent open at wide open throttle regardless of engine speed. This setup gives you consistent exhaust tone and improved throttle response throughout the RPM range.
On this platform, the exhaust valve system required extensive research and development. Relocating, disconnecting, or improperly modifying the valves can trigger the check engine light and lead to drivability concerns. Unlike older vacuum actuated OEM exhaust valves, these electronic actuators maintain constant tension on the valve bodies. Removing the actuators does not allow the valves to default to an open position through spring pressure. The included hardware is engineered to maintain correct actuator preload and valve movement. This ensures reliable operation, prevents fault codes, and protects overall performance. If you are upgrading your exhaust system, maintaining proper electronic valve function is critical for long term reliability and optimal results.
Sound:
Upgrade your driving experience with a performance exhaust system engineered for enthusiasts who want precise sound control and refined tone across the entire RPM range. This system delivers a deeper, higher pitched exhaust note that stands apart from the factory setup, while maintaining comfort during daily driving.
