The RENNVOX downpipe with 200 Cell Catalytic Converter is under development for the Land Rover Defender 110 / 130 P400 (L663), powered by the 3.0L turbocharged inline-six mild hybrid petrol (P400). Developed with a vehicle-specific approach, this application focuses on enhancing exhaust character while respecting the distinctive engineering of the platform.

The proposed downpipe application incorporates a 200 Cell Catalytic Converter concept. Final converter configuration, sensor integration, emissions suitability and compatibility will be confirmed during development; road-use legality varies by jurisdiction. The hybrid powertrain requires additional validation of operating modes and exhaust-system integration.
