Milltek has developed two standout exhaust solutions for the Porsche 992-generation 911 Carrera GTS, S, 4S, and Dakar. Designed to transform both the sound and driving experience, these systems address the restrictions of factory emissions hardware while giving enthusiasts the durability and refinement expected from one of the UK’s premier performance exhaust manufacturers. Available through Bulletproof Automotive, both the Valved GPF-OPF-Back system and the Titanium Signature Series Valved Catback system bring distinct advantages to the table.
Since 2018, new Porsche 992 models have been fitted with gasoline particulate filters to meet global emissions regulations. While effective at reducing pollutants, these filters significantly mute the exhaust note. Milltek’s GPF-OPF-Back system is specifically engineered to offset that loss, restoring tone and character while preserving drivability.
This system uses 76mm (3-inch) diameter piping for improved flow and comes complete with connecting pipes, left and right valved outlet pipes, and dual inner tailpipes. The system is fully compatible with Porsche Sport Exhaust (PSE) equipped cars and works with factory tips, making it an ideal upgrade for owners seeking a subtle yet effective enhancement. By retaining the factory trims, the visual appearance remains OEM while the driving experience takes a clear step forward in both sound and response.
Applications include the Porsche 992; 911 Carrera S and 4S (2019+), Carrera GTS and 4 GTS (2021+), and the Dakar (2022+), all powered by the 3.0L twin-turbo flat-six engine. The result is a more engaging sound profile that matches the Porsche’s performance pedigree.
For those seeking the ultimate combination of weight reduction, sound, and durability, Milltek offers the Titanium Signature Series Valved Catback system. This system replaces the stock catback unit and provides a sharper, more aggressive exhaust note with multiple configuration options to suit individual sound preferences.
Crafted entirely from titanium, this system offers significant weight savings compared to stainless steel and excels in high-temperature environments. Titanium’s resistance to corrosion also ensures long-term reliability, even under demanding use. With 76mm piping, the system improves exhaust flow for performance gains while retaining the convenience of OEM tip fitment and PSE compatibility.
Each kit includes link pipes to the OE catalytic converters, valved outlet pipes, and dual inner outlet pipes. The valved design allows drivers to adjust sound levels as desired, from refined cruising to a raw, motorsport-inspired tone at higher revs. Whether fitted to the Carrera GTS, Carrera S, or the adventurous Dakar, the Signature Series system delivers a high-performance soundtrack that matches the car’s engineering excellence.
Milltek has established itself as one of the most respected names in performance exhausts, with products available in more than 90 countries. With a dedicated research and development team, the company continues to push innovation across a wide range of platforms. Manufactured in the UK with a focus on precision, performance, and sound, Milltek exhausts are built for enthusiasts who expect more from their driving experience.
Both the Milltek Valved GPF-OPF-Back and Titanium Signature Series Valved Catback exhaust systems for the Porsche 992 Carrera GTS, S, 4S, and Dakar are available now through Bulletproof Automotive.
