SOUL 992.2 GTS Sport Cat Downpipe – Unleash the True Sound of Your Porsche 911 GTS
 
Porsche set a new benchmark with the 992.2 Carrera GTS - the first road-legal 911 to feature a hybrid-assisted powertrain. Unlike recent 911 models, the GTS is equipped with a single large turbocharger, instead of two smaller turbos. However, strict European emissions and sound regulations required Porsche to fit the car with an oversized muffler and restrictive catalytic converters.

The result? A muted flat-six soundtrack and a loss of the thrilling big-turbo character that true enthusiasts expect. The factory system holds back both performance and emotion, leaving drivers wanting more from their 992.2 GTS experience.

The SOUL 992.2 GTS Sport Cat Downpipe transforms your driving experience by unlocking the raw, turbocharged voice of the 992.2 Carrera GTS. Featuring a high-flow sport catalytic converter, this system dramatically reduces backpressure while maintaining emissions compliance and everyday drivability. With precision engineering that integrates seamlessly with Porsche’s factory particulate monitoring system, you can enjoy exhilarating sound and performance—without check engine lights or the need for OBD blockers.

Decatted Heat-Shielded Downpipe

Developed specifically for the Porsche 911 992.2 Carrera GTS, the 9M Decatted Heat-Shielded Downpipe is a direct bolt-on performance exhaust upgrade designed to reduce weight, improve exhaust flow and release more of the character of the flat-six engine.

Fits:

• Porsche 992.2 Carrera 2 GTS 3.6L 2024>>
• Porsche 992.2 Carrera 4 GTS 3.6L 2024>>

Diagram Ref No 7

Available in stainless steel or lightweight titanium, the downpipe weighs approximately 9kg less than the factory component while retaining a straightforward bolt-on installation with no cutting or welding required.

Designed to fit all worldwide Porsche 911 992.2 Carrera GTS models from 2025 onwards.

What Does the Downpipe Do?

The downpipe carries hot exhaust gases away from the engine and into the remaining exhaust system.

The original component incorporates emissions-control hardware that creates a restriction within the exhaust path. The 9M decatted design removes this restriction, allowing exhaust gases to flow more freely through the system.

The result is a more performance-focused exhaust configuration with a stronger, more natural flat-six exhaust note.

Why Upgrade?

For owners looking for a more engaging exhaust sound and reduced vehicle weight, the 9M downpipe provides several advantages over the factory component.

The less restrictive design allows the engine to expel exhaust gases more freely, while removing approximately 9kg compared with the factory assembly provides a worthwhile weight saving.

The system has also been developed to deliver a stronger flat-six exhaust note without introducing unwanted drone or poor resonance.

Key benefits include:

• Approximately 9kg lighter than the factory component
• Less restrictive decatted exhaust path
• Improved exhaust gas flow
• More pronounced flat-six exhaust sound
• Designed to avoid unwanted drone and poor resonance
• Heat-shielded construction
• Stainless steel or titanium options
• Direct bolt-on installation
• No cutting or welding required

Heat-Shielded Construction

Exhaust downpipes operate at extremely high temperatures, particularly during sustained performance driving.

The heat-shielded construction helps manage radiant exhaust heat around the downpipe and surrounding components, making thermal management an important part of the design rather than simply reducing restriction.

Stainless Steel or Titanium

The 9M downpipe is available in two material options.

Stainless steel provides excellent durability, corrosion resistance and long-term performance, making it an excellent choice for both road and performance use.

Titanium provides a more exotic lightweight alternative for owners looking to maximise weight reduction and use premium motorsport-inspired materials.

Bolt-On Installation

The downpipe has been engineered as a bolt-on replacement for the factory component.

No cutting or welding is required, making installation cleaner and avoiding permanent modification of the exhaust system during fitment.

Important Road Use Information

This is a decatted performance component and removes emissions-control equipment from the exhaust system. As a result, it may not comply with road vehicle emissions regulations, inspection requirements or type approval rules in some countries.

Customers should check local regulations before installation. It may be intended for motorsport, competition or other permitted off-road applications where local legislation requires catalytic converters to remain fitted for road use.

Downpipe & Performance Exhaust Upgrades

Upgrading the downpipe is an effective way to reduce exhaust restriction, increase the character of the flat-six exhaust note and remove weight from the Porsche 911 992.2 Carrera GTS.

The 9M decatted downpipe combines a freer-flowing exhaust path with heat-shielded construction and a substantial reduction in weight compared with the original component. With stainless steel and titanium versions available, owners can choose between a durable performance upgrade or a more weight-focused premium solution.

For Porsche 992.2 Carrera GTS owners looking for a more engaging exhaust experience, reduced weight and straightforward bolt-on installation, the 9M downpipe provides a purpose-designed upgrade without requiring cutting or welding.

Sports Catted Heat-Shielded Downpipe 

Developed specifically for the Porsche 911 992.2 Carrera GTS, the 9M Sports Catted Heat-Shielded Downpipe provides a less restrictive alternative to the factory exhaust component while retaining a sports catalytic converter.

Fits:

• Porsche 992.2 Carrera 2 GTS 3.6L 2024>>
• Porsche 992.2 Carrera 4 GTS 3.6L 2024>>

Diagram Ref No 7

Approximately 5kg lighter than the factory part, it combines improved exhaust flow with reduced weight and a more pronounced flat-six exhaust note. The system is designed to operate without triggering an engine management light, with no OBD blocker required.

Available in stainless steel or lightweight titanium and designed as a direct bolt-on installation with no cutting or welding required.

Fits all Porsche 911 992.2 Carrera GTS models from 2025 onwards worldwide.

What Does the Sports Catted Downpipe Do?

The downpipe carries hot exhaust gases away from the engine and into the remainder of the exhaust system.

Factory downpipes must balance emissions control, refinement and production requirements, which can restrict exhaust flow. The 9M sports catted design uses a more performance-focused exhaust path while retaining catalytic converter functionality.

This helps improve exhaust flow while providing a more engaging exhaust note than the standard system.

Why Upgrade?

The 9M Sports Catted Downpipe is designed for owners who want improved exhaust sound, reduced weight and freer exhaust flow without moving to a fully decatted setup.

Compared with the factory component, it offers an approximate 5kg weight saving while retaining a sports catalyst. The exhaust note is also enhanced to bring out more of the flat-six character without introducing unwanted drone or poor resonance.

Another important advantage is compatibility with the vehicle's engine management system. The downpipe is designed to operate without illuminating the engine management light, meaning an additional OBD blocker is not required.

Sports Catalyst Design

Unlike the 9M decatted version, this downpipe retains a sports catalytic converter.

This provides a useful middle ground for owners looking for a freer-flowing performance exhaust while retaining catalytic exhaust treatment.

Heat-Shielded Construction

Downpipes operate at extremely high temperatures, making thermal management particularly important in the tightly packaged engine bay of a modern Porsche 911.

The integrated heat shielding helps control radiant heat around the exhaust system and nearby components while maintaining the benefits of the performance downpipe design.

Stainless Steel or Titanium

The 9M Sports Catted Downpipe is available in two material options.

Stainless steel provides excellent durability, corrosion resistance and long-term performance, making it well suited to regular road and performance use.

Titanium offers a premium, lightweight alternative for owners looking to further optimise their performance exhaust system with motorsport-inspired materials.

Direct Bolt-On Installation

The downpipe is engineered as a direct bolt-on replacement for the original component.

No cutting or welding is required, simplifying installation and avoiding the fabrication work associated with universal or modified exhaust components.

Important Road Use Information

Although this version retains a sports catalytic converter, emissions and road-use regulations vary between countries and regions. Fitment of an aftermarket sports catalyst does not automatically guarantee compliance with local emissions testing, type approval or road vehicle regulations.

Customers should confirm local requirements before installation.

Sports Cat Downpipes & Exhaust Upgrades

A sports catted downpipe provides an effective compromise for Porsche 992.2 Carrera GTS owners looking for improved exhaust flow and a more engaging flat-six sound while retaining a catalytic converter.

The 9M system combines a sports catalyst with heat-shielded construction, direct bolt-on installation and an approximate 5kg weight reduction compared with the factory component.

With stainless steel and titanium options available, it is an ideal upgrade for owners looking to improve the sound and performance-focused character of their Porsche 911 992.2 Carrera GTS without choosing a fully decatted exhaust configuration.
