Unlock the unmistakable sound of Porsche's naturally aspirated flat-six with the RENNVOX Full Exhaust System, developed for the Porsche 911 991.1 Carrera, Carrera S and Carrera GTS.

Featuring performance exhaust headers, high-flow 200 cell sports catalytic converters and a complete performance exhaust system, this integrated upgrade is designed to enhance exhaust flow, sharpen the engine's acoustic character and deliver a more engaging driving experience.

A More Expressive Naturally Aspirated Flat-Six Sound

The Porsche 911 991.1 Carrera range is celebrated for its naturally aspirated flat-six engines. The RENNVOX system builds on that character, delivering a richer exhaust tone at lower engine speeds and a more pronounced, motorsport-inspired soundtrack as the revs climb.

From the distinctive flat-six burble to the sharper exhaust note under acceleration, the system is designed to provide an engaging sound experience throughout the rev range.

Performance Headers & 200 Cell Sports Catalytic Converters

Unlike a conventional cat-back exhaust, the RENNVOX Porsche 911 991.1 Full Exhaust System incorporates performance headers and 200 cell sports catalytic converters as part of a complete exhaust upgrade.

The performance headers are designed to improve the exhaust gas path from the engine, while the high-flow sports catalytic converters provide a less restrictive alternative to conventional factory catalyst configurations.

Working together, these components are designed to promote efficient exhaust gas flow and allow more of the naturally aspirated engine's distinctive sound to be heard.

Premium T304 Stainless Steel Construction

Manufactured using T304 stainless steel, the RENNVOX exhaust system combines corrosion resistance, durability and premium construction.

Developed for the Porsche 911 991.1 platform, the system provides a comprehensive exhaust upgrade for owners seeking improved acoustic character and a premium performance exhaust solution.

Frequently Asked Questions

What is included in the RENNVOX Porsche 911 991.1 Full Exhaust System?

The system includes performance exhaust headers, 200 cell sports catalytic converters and a complete performance exhaust system. It is designed as a comprehensive exhaust upgrade rather than a cat-back-only replacement.

Does this exhaust fit the Porsche 911 Carrera, Carrera S and Carrera GTS?

The system is offered for the Porsche 911 991.1 Carrera, Carrera S and Carrera GTS. Fitment must be confirmed for the specific vehicle before ordering.

What is the difference between a full exhaust system and a cat-back exhaust?

A cat-back exhaust generally replaces the exhaust components downstream of the catalytic converters. The RENNVOX Full Exhaust System also incorporates performance headers and 200 cell sports catalytic converters, providing a more comprehensive upgrade.

What are 200 cell sports catalytic converters?

200 cell sports catalytic converters use a lower-density catalyst substrate designed to reduce exhaust restriction while retaining catalytic converters within the exhaust system. Their emissions performance and road legality depend on the specific application and applicable regulations.

How will the RENNVOX exhaust change the sound of my Porsche 911?

The system is designed to enhance the naturally aspirated flat-six soundtrack, producing a deeper exhaust tone and a more pronounced sound under acceleration. Actual sound characteristics vary with vehicle specification and operating conditions.

Will this exhaust increase horsepower?

The system is designed to improve exhaust flow, but specific horsepower or torque gains have not been established for this listing. Any performance increase will depend on the vehicle, installation and engine calibration.

Does the RENNVOX full exhaust require engine tuning?

Tuning requirements depend on the vehicle's engine management system and exhaust configuration. Professional installation and diagnostic checks are recommended when replacing factory headers and catalytic converters.

Is the RENNVOX Porsche 911 exhaust road legal in Australia?

Road legality depends on applicable emissions, noise and vehicle modification regulations. The inclusion of 200 cell sports catalytic converters does not automatically establish road-use compliance. Confirm local requirements before installation or road use.
