Porsche 992 GT3 / GT3 RS – EPA-Compliant 400 Cell Catted Downpipes
Engineered for the 4.0L Naturally Aspirated Flat-Six • High-Flow • Compliant •
Introducing Our NEW 400 Cell EPA-Compliant Downpipes for 992 GT3
The Porsche 992 GT3 and GT3 RS are motorsport-derived machines built around a 9,000 RPM naturally aspirated flat-six. While the factory catalysts prioritize restriction and sound control, our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce exhaust backpressure, improve high-RPM breathing, and enhance the engine’s unmistakable motorsport character — all while maintaining emissions compliance standards.
This upgrade preserves the integrity of the GT3 platform while allowing the engine to operate with greater efficiency and clarity at redline.
Why Upgrade to 400 Cell?
- EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust efficiency while maintaining compliance standards.
- Improved High-RPM Flow: Reduced restriction enhances top-end breathing and throttle precision.
- Enhanced Motorsport Character: Sharper, more defined exhaust note at elevated RPM.
- Track-Focused Performance: Optimized for spirited driving and circuit use without sacrificing reliability.
Engineering & Performance
- Optimized Flow Architecture: Designed to minimize backpressure while preserving catalyst efficiency.
- Mandrel-Bent Tubing: Smooth internal transitions for consistent exhaust velocity.
- Precision TIG Welding: Built to withstand extreme exhaust temperatures during sustained high-RPM operation.
- Direct OEM Bolt-On Installation: Utilizes factory mounting locations for seamless fitment.
- Engineered to Pair with Valvetronic Exhaust Systems
Sound Character
- Stock Exhaust + Downpipes: Noticeable increase in clarity and presence with improved high-frequency resonance.
- Valvetronic Exhaust + Downpipes: Maximum transformation — sharper transitions, heightened induction character, and a more race-inspired signature.
Construction & Durability
- Premium high-grade stainless steel construction
- High-temperature resistant 400 cell catalyst cores
- OEM-style sensor placement for proper operation
