Audi RSQ8 / SQ8 / SQ7 – EPA-Compliant 400 Cell Catted Downpipes
Unlock the Full Potential of the 4.0T Twin-Turbo V8 • High-Flow • Compliant •
Introducing Our NEW 400 Cell EPA-Compliant Downpipes for Audi 4.0T
The 4.0T twin-turbo V8 powering the Audi RSQ8, SQ8, and SQ7 delivers immense performance — but factory catalyst restrictions hold it back. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to increase exhaust flow, enhance turbo efficiency, and dramatically sharpen the vehicle’s sound profile — all while maintaining emissions compliance standards.
This is the foundation of true 4.0T performance.
Why Upgrade to 400 Cell?
- EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust velocity while maintaining compliance standards.
- Faster Turbo Spool: Reduced backpressure improves throttle response and mid-range torque delivery.
- Sharper Exhaust Note: Enhanced turbo acoustics with deeper low-end presence and more aggressive top-end tone.
- Optimized Performance Balance: Noticeable gains without compromising daily drivability.
