• 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.
