Description
Designed specifically for the 4.0T EA825 twin-turbo V8 platform, the Untd. Performance 200 Cell Downpipe with Heat Shield is engineered to improve exhaust flow while retaining a high-flow catalytic converter. The upgraded design helps reduce exhaust restriction, improve turbocharger response, and deliver a more aggressive exhaust note without using a completely catless configuration.
Featuring a 200-cell high-flow catalytic converter, this downpipe provides a less restrictive exhaust path compared to the factory system. The included heat shield provides additional thermal protection around the downpipe and surrounding components, making it an ideal performance upgrade for the Audi SQ8, Audi RSQ8, and Lamborghini Urus.
Key Features
200 Cell High-Flow Catalytic Converter – Increased Flow:
The Untd. Performance downpipe utilizes a 200-cell high-flow catalytic converter designed to provide significantly improved exhaust flow compared to the restrictive factory catalytic converter. The increased flow can help reduce exhaust backpressure and allow the EA825 twin turbochargers to operate more efficiently.
Improved Turbo Response & Performance:
The freer-flowing downpipe allows exhaust gases to exit the EA825 turbochargers more efficiently. When paired with an appropriate ECU calibration, the reduced restriction can help improve turbo response, throttle response, horsepower, and torque.
Aggressive EA825 V8 Sound:
The 200-cell high-flow design enhances the exhaust character of the 4.0T twin-turbo V8, producing a deeper and more aggressive exhaust tone while retaining more sound control than a fully catless setup. Turbo spool and exhaust notes become more pronounced under acceleration.
Integrated Heat Shield:
The included heat shield helps reduce radiant heat from the downpipe and provides additional thermal protection for surrounding engine-bay components. This is especially beneficial around the high-temperature exhaust and turbocharger environment of the EA825 V8.
Stainless Steel Construction:
Manufactured from high-quality stainless steel and engineered to withstand the extreme temperatures and exhaust pressures generated by the EA825 twin-turbo V8. Precision-welded construction provides excellent durability for both street and performance applications.
Direct-Fit / Bolt-On Design:
Designed specifically for compatible Audi SQ8, Audi RSQ8, and Lamborghini Urus 4.0T EA825 applications, providing a straightforward replacement for the factory downpipe while maintaining compatibility with suitable OEM and aftermarket exhaust components.
Installation Hardware Included:
The downpipe includes replacement gaskets, bolts, and required installation hardware to help ensure a proper fit and secure installation. Supplied hardware helps simplify installation while providing the necessary components for proper sealing and mounting.
Tune Recommended for Optimal Performance:
An ECU tune is recommended to take full advantage of the increased exhaust flow provided by the 200-cell downpipe. Proper calibration can help optimize boost control, fueling, throttle response, and overall engine performance.
⚠️ Check Engine Light Warning
Depending on the vehicle’s model year, ECU software, emissions configuration, and calibration, a Check Engine Light (CEL) may occur after installing a 200-cell high-flow downpipe.
The change in exhaust flow and catalytic converter characteristics can alter the exhaust gas readings monitored by the ECU. A compatible ECU tune may be recommended or required to properly calibrate the vehicle and address potential catalyst-efficiency-related fault codes.
For optimal performance, drivability, and compatibility, professional ECU tuning is recommended.
Why Upgrade?
The factory EA825 exhaust system is designed around emissions requirements, noise regulations, and OEM drivability. As a result, the factory catalytic converter can create additional restriction in the exhaust system.
The Untd. Performance 200 Cell Downpipe replaces the factory downpipe with a higher-flowing system designed to improve exhaust gas flow from the EA825’s twin turbochargers.
The 200-cell catalytic converter provides a performance-oriented alternative to the factory unit, offering increased exhaust flow while retaining a high-flow catalytic element. Combined with the included heat shield, the system is designed to improve both exhaust flow and thermal management.
When paired with ECU tuning and supporting modifications, the Untd. Performance 200 Cell Downpipe can help improve turbo response, throttle response, power potential, and overall exhaust character while maintaining a catalytic converter-based configuration.
