Fabspeed Valvetronic Nordschleife Catback Exhaust System for Porsche 992 GT3 & GT3 RS (2022–Present)

Description

Elevate your 2022 + Porsche 992 GT3 (including GT3 RS and Speedster) with the Fabspeed Valvetronic Nordschleife Cat-Back Exhaust System — a precision-engineered, performance-driven upgrade that blends track-inspired sound, measurable gains and premium build quality. Featuring a 70 mm (≈2.75″) diameter investment-cast X-pipe, aerospace-grade Helical Limited exhaust valves from the UK and T304L mandrel-bent stainless– this system retains your vehicle’s PSE (Porsche Sport Exhaust) valve functionality while delivering a richer, more aggressive soundtrack and quicker throttle response. With real dyno results and weight savings built in, it’s the upgrade your GT3 / GT3 RS has been waiting for.

Fitment Notes

• Compatible with 2022-present Porsche 992 GT3, GT3 RS and Speedster models. 

• Designed to retain the factory PSE (valved exhaust) system functionality — the system is valvetronic, meaning you get “quiet” or “aggressive” modes via your OEM valve control. 

• Replacement is direct-fit (cat-back) for the factory rear muffler section/back end of the exhaust; no cutting or welding required for standard models.

• Note: Some listings reference “w/o monitored GPF” or “global market” compatibility — verify if your region has a Gasoline Particulate Filter/monitored system. 

• Legal/regulation check: Although Fabspeed states “fully emissions-legal in all 50 states” for this system, always confirm local regulations and emissions compliance for your region.

Included

• Full cat-back system for the Porsche 992 GT3/GT3 RS/Speedster (2022+) including mid-section, muffler section, tailpipes with customer choice of tip style. 

• Aerospace-grade Helical Limited exhaust valve assemblies (UK-made) integrated into the system for valved operation.

• Investment cast 70 mm X-pipe linking the two flat-six banks for scavenging optimization.

• Choice of tailpipe tip finishes (e.g., matte carbon-fiber, polished stainless, brushed stainless) depending on variant.

• All required hardware and gaskets for bolt-on installation (no fabrication required). 

• Backed by Fabspeed’s Lifetime Warranty.

Product Specs

• Material: Mandrel-bent T304L stainless steel tubing (14-16ga wall); investment cast X-pipe; high-grade Helical Limited valves. 

• Pipe diameter: Upgraded from the factory ~2.5″ to 2.75″ (≈70 mm) for improved flow.

• Power gains (dyno tested): +14 whp at 4,200 rpm and +17 ft-lb torque at 4,200 rpm. 

• Weight savings: ≈ 5 lbs (≈2.3 kg) lighter than factory system. Some sources show up to 7 lbs (≈3.2 kg) for certain variants. 

• Fitment year: 2022+ (992 GT3/GT3 RS/Speedster) worldwide.

Product Features

• Track-Inspired Sound & Dynamic Performance: With PSE valves open, the system transforms the flat-six’s character into a high-reving, exotic sports car soundtrack — without compromising the “quiet” mode for normal driving.

• Optimized Flow Design: The investment cast 70 mm X-pipe delivers effective scavenging across the twin bank layout, improving exhaust gas flow and resulting in measurable power and torque gains. 

• Premium Build Quality: High-quality materials, precision CAD/CAM engineering (3D laser scanned fitment), aerospace-grade valve hardware (Helical Limited UK) and durable manufacturing ensure long-term reliability.

• Weight Reduction for Better Agility: Shedding ~5-7 lbs from the rear/muffler section helps reduce unsprung mass, improving throttle response, handling feel and overall vehicle dynamics. 

• Retained OEM Valve Functionality: Keeps your factory PSE valves and controls for both quiet and aggressive modes — giving you full drive-mode flexibility. 

• Emissions-Friendly & DIY Install: Designed as a drop-in bolt-on cat back system with stated emissions legality in 50 states (for applicable variant) and no cutting or welding required.
