Upgrade the exhaust path of your Porsche 911 Turbo / Turbo S with the RENNVOX Downpipe with 200 Cell Catalytic Converter. Developed for the 992.2 platform and 3.7L flat-6 twin-turbo application, this vehicle-specific performance component is designed to reduce exhaust restriction while retaining a high-flow catalytic converter configuration.

The factory exhaust and catalytic converter assembly must balance emissions control, noise, refinement and production requirements. The RENNVOX upgrade uses a 200 Cell Catalytic Converter to support improved exhaust gas flow, sharper response and greater performance potential, while retaining a catalytic converter for a more road-oriented configuration than a catless system.

On the Porsche 911 Turbo / Turbo S, the exhaust components in this area play an important role in gas flow and engine breathing. The RENNVOX design is intended to help the turbocharged engine evacuate exhaust gases more efficiently and provide a stronger foundation for improved response and performance when paired with a compatible vehicle calibration.

Fitment is application-specific to the listed 992.2 chassis and 3.7L flat-6 twin-turbo configuration. Professional installation is recommended, and ECU calibration requirements can vary depending on the exact vehicle, local market specification and other modifications.
