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.
