Audi C8 RS6 / RS7 – EPA-Compliant 400 Cell Catted Downpipes
Engineered for the 4.0T Twin-Turbo V8 • High-Flow • Compliant •
Introducing Our NEW 400 Cell EPA-Compliant Downpipes for C8 RS6 / RS7
The Audi C8 RS6 and RS7 combine executive refinement with supercar-level performance, powered by the formidable 4.0T twin-turbo V8. While factory catalysts restrict exhaust flow and mute the engine’s full character, our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce backpressure, enhance turbo efficiency, and unlock a deeper, more commanding exhaust tone — all while maintaining emissions compliance standards.
This upgrade forms the foundation of serious 4.0T performance.
Why Upgrade to 400 Cell?
- EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust efficiency while maintaining compliance standards.
- Improved Turbo Spool & Mid-Range Response: Reduced restriction sharpens throttle input and power delivery.
- Enhanced Exhaust Character: Deeper tone with stronger turbo acoustics and more pronounced high-RPM presence.
- Street & Performance Balanced: Noticeable gains without compromising daily refinement.
Performance & Engineering
- Optimized Flow Architecture: Minimizes backpressure while preserving catalyst efficiency.
- Mandrel-Bent Tubing: Smooth internal transitions for maximum exhaust velocity.
- Precision TIG Welding: Built to endure sustained high exhaust temperatures and boost levels.
- Direct OEM Bolt-On Installation: Utilizes factory mounting locations for straightforward installation.
- Engineered to Pair Seamlessly with Valvetronic Exhaust Systems
Sound Transformation
- Stock Exhaust + Downpipes: Noticeable increase in depth and turbo presence with enhanced exhaust clarity.
- Valvetronic Exhaust + Downpipes: Maximum transformation — stronger presence, sharper transitions, and a true Audi Sport-inspired signature.
Construction & Durability
- Premium high-grade stainless steel construction
- High-temperature resistant 400 cell catalyst cores
- OEM-style sensor placement for proper operation
- Engineered for long-term reliability under high-performance conditions
Unleash the full potential of your C8 RS6 or RS7 — starting at the source.
