Does it fit the Porsche 992.2 Carrera GTS Hybrid?
Yes. It is engineered for the 992.2 Porsche 911 Carrera GTS, Carrera 4 GTS and Targa 4 GTS with the 3.6L twin-turbo flat-six hybrid, from 2025 onward. It is a direct fit to the factory mounting points.
Which material should I choose, Inconel or stainless?
Both are offered. Inconel 625 is an F1-grade superalloy that gives the biggest weight saving and the highest heat tolerance, so it is the choice for the lightest, most premium build. The 304 stainless steel option delivers the same design and valvetronic function at a lower price.
What downpipe options are there?
You can run the cat-back system on its own, or add a matching high flow downpipe. Choose 100 cell or 200 cell sport catalysts for a road-legal setup that frees up flow, or the race decat downpipe for track use where emissions equipment is not required. Downpipes are available in both stainless and Inconel to match your system.
Does the valvetronic system let me control the volume?
Yes. The valvetronic silencers are fully bypassable, so the exhaust is quiet and refined with the valves closed and loud and open under load. It works with the car's driving modes.
How much weight does it save?
A large amount over the factory system. The Inconel 625 rear silencer weighs about 7.5 kg and the catalyst pipes about 4.7 to 4.85 kg, with the ultra-light Inconel X-pipe and carbon fibre tips reducing weight further.
