RENNVOX Porsche 911 992.1 / 992.2 GT3 & GT3 RS Full Exhaust System

Experience more of the unmistakable character of Porsche's naturally aspirated flat-six with the RENNVOX Full Exhaust System with 200 Cell Sports Catalytic Converters, developed for the Porsche 911 992.1 and 992.2 GT3 and GT3 RS.

Designed as a complete exhaust upgrade, the RENNVOX system replaces the factory exhaust and catalytic converter sections with a freer-flowing performance system incorporating 200 cell sports catalytic converters. By reducing exhaust restriction through the complete system, the RENNVOX exhaust allows the high-revving GT3 engine to deliver a sharper, more aggressive and more engaging exhaust note.

The high-flow 200 cell sports cats provide greater exhaust gas flow than the more restrictive factory catalytic converters while maintaining a catted configuration. Combined with the RENNVOX performance exhaust, they allow more of the GT3's distinctive flat-six character to be heard, particularly as the engine climbs through the rev range.

The valved exhaust design provides greater control over the character of the system. With the valves closed, the exhaust delivers a more restrained sound suited to everyday driving. Open the valves and the system reveals a significantly more aggressive exhaust note that better reflects the character of Porsche's GT3 and GT3 RS.

Manufactured from premium stainless steel, the RENNVOX system is engineered to withstand the temperatures and demands associated with high-performance road and track use. Precision fabrication and vehicle-specific construction ensure accurate fitment to the Porsche 911 992 GT3 platform.

For owners wanting a more comprehensive upgrade than a cat-back exhaust alone, the RENNVOX Full Exhaust System combines high-flow 200 cell sports cats, improved exhaust flow and a valved performance exhaust in one integrated package.

Frequently Asked Questions

Which Porsche models does this RENNVOX exhaust fit?

The system is designed for compatible Porsche 911 992.1 and 992.2 GT3 and GT3 RS models. Vehicle specifications can vary between production years and markets, so fitment should be confirmed before ordering.

What is included in the RENNVOX full exhaust system?

The system combines the RENNVOX valved performance exhaust with high-flow 200 cell sports catalytic converters, creating a complete exhaust upgrade for the Porsche 911 GT3 and GT3 RS.

What is the difference between this full exhaust and the RENNVOX cat-back exhaust?

The RENNVOX cat-back system retains the factory catalytic converters. This full exhaust system also replaces the factory catalytic converter sections with 200 cell sports catalytic converters, creating a freer-flowing exhaust system from the catalytic converter section rearwards.

What are 200 cell sports catalytic converters?

200 cell sports catalytic converters use a lower-density catalyst substrate than typical factory catalytic converters. This provides a less restrictive path for exhaust gases while retaining catalytic converters within the exhaust system.

Does the exhaust retain valve functionality?

Yes. The RENNVOX system features a valved exhaust configuration, allowing the exhaust character to change according to valve operation.

How does the RENNVOX full exhaust change the sound of the GT3?

The combination of the freer-flowing exhaust and 200 cell sports cats allows more of the naturally aspirated flat-six exhaust note to be heard. The result is a sharper and more aggressive sound, with the difference becoming increasingly pronounced as engine speed rises.

Is the system suitable for road and track vehicles?

The RENNVOX exhaust is engineered for high-performance applications; however, emissions and noise requirements vary between jurisdictions. Owners should confirm the regulations applicable to their vehicle and intended use.

Is tuning required after fitting the full exhaust?

Requirements can vary according to vehicle specification, market and engine management calibration. Professional installation and appropriate diagnostic checks are recommended when replacing factory catalytic converters with high-flow sports cats.
