Description
Disclaimer: This item is made to order. Lead time 6-10 weeks.
The CARGRAPHIC Sport Catalytic Converter Set for the Porsche 997.1 Carrera is designed to improve exhaust flow, reduce backpressure, enhance engine response, and increase performance while maintaining OBD2-compliant catalyst functionality.
This version features a separated exhaust flow design with two large-volume 200 CPSI Ø120mm HD OBD2 TRIMETAL catalytic converters. The increased catalyst housing volume and optimized expansion space are designed to maximize exhaust flow while maintaining efficient catalyst operation.
Manufactured in Germany from lightweight SS304L stainless steel, the system is mandrel-bent using CNC pipe-bending equipment to maintain a consistent pipe diameter throughout the exhaust system. Reinforced laser-cut flanges and brackets provide additional strength and durability.
The result is a high-performance catalytic converter system engineered for Porsche 997.1 Carrera applications, with improved throttle response, freer-revving characteristics, enhanced exhaust acoustics, and reduced backpressure.

Exhaust Flow & Performance
The CARGRAPHIC catalytic converter set is engineered around maximizing exhaust flow while maintaining a high-performance catalyst configuration.
The Ø120mm housings provide increased catalyst volume and expansion space, while the 200 CPSI HD OBD2 TRIMETAL catalytic converters are designed to provide a freer-flowing exhaust path.
Reduced backpressure can improve engine breathing, contributing to improved throttle response, freer-revving characteristics, and increased power and torque.
CARGRAPHIC states that the system can provide up to 10kW (13 PS) of additional power and up to 18Nm of additional torque, depending on the overall vehicle configuration and supporting modifications.
Sound & Acoustics
The SUPER SOUND Export Version is designed to enhance the exhaust sound of the Porsche 997.1 Carrera while maintaining a model-specific acoustic character.
CARGRAPHIC specifically states that the system is designed to operate without drone, resonance, or vibration, including when used with additional CARGRAPHIC exhaust components.
The result is a more aggressive and enhanced exhaust note while remaining consistent with the characteristic sound of the Porsche marque.
OBD2 & ECU Compatibility
The catalytic converter set is designed around OBD2-compliant catalyst technology, with CARGRAPHIC stating that no Check Engine Light (CEL) and no DME/ECU programming are required for the intended application.
However, this product is specifically sold as a Motorsport / Export Version and is not intended for public-road use.
Motorsport & Legal Notice
IMPORTANT: The CARGRAPHIC SUPER SOUND Export Version is intended solely for motorsport, track, and race applications.
It is not road legal and is not designed to meet federal emissions standards in the USA. CARGRAPHIC/HJS states that these products are not California Air Resources Board (CARB) certified and not EPA certified.
Customers are responsible for determining whether the product is legal for use in their specific jurisdiction and application.
Installation
The CARGRAPHIC Sport Catalytic Converter Set is designed for straightforward installation using olive, band-clamp, and sleeve connections that allow adjustment and alignment during installation.
The system uses reinforced laser-cut flanges and brackets for additional strength. Factory hardware is reused during installation.
Professional installation is recommended, particularly for motorsport applications where proper exhaust alignment and sealing are critical.
