Porsche 992 Turbo / Turbo S – EPA-Compliant 400 Cell Catted Downpipes
Precision Engineered for the 3.8L Twin-Turbo Flat-Six • High-Flow • Compliant •
Introducing Our NEW 400 Cell EPA-Compliant Downpipes for 992 Turbo
The Porsche 992 Turbo and Turbo S represent the pinnacle of modern forced-induction performance. While the 3.8L twin-turbo flat-six delivers exceptional power from the factory, restrictive catalysts limit exhaust efficiency and mute the engine’s true character. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce backpressure, enhance turbo responsiveness, and refine the exhaust signature — all while maintaining emissions compliance standards.
This upgrade elevates performance while preserving the precision expected from Porsche.
Why Upgrade to 400 Cell?
- EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust efficiency while maintaining compliance standards.
- Improved Turbo Response: Reduced restriction enhances spool characteristics and throttle precision.
- Enhanced Exhaust Presence: Deeper tone with improved clarity at higher RPM.
- Maintained Drivability: Noticeable gains without sacrificing refinement or daily comfort.
Engineering & Performance
- Optimized Flow Architecture: Minimizes backpressure while preserving catalyst efficiency.
