The Kline Innovation Valvetronic Exhaust System is a fully handcrafted, valve-controlled cat-back exhaust for the Porsche 911 992 Carrera, Carrera S, Carrera 4, Carrera 4S and Carrera GTS with the 3.0L twin-turbo flat-six. Built in Bucharest, Romania by one of the most respected names in bespoke exhaust engineering, it transforms the 992 into a razor-sharp, aggressive-sounding sports car while keeping full daily drivability and zero cabin drone.
It fits both the 992.1 (2019-2024) and 992.2 generations, and works with cars fitted with Porsche Sport Exhaust (PSE) or the standard exhaust. Choose between aerospace-grade Inconel 625 or 304 stainless steel, four downpipe/catalytic options, and OEM or carbon fiber tips to build the exact system you want.

Kline uses its trademark perfect X-pipe geometry and harmonically tuned silencer geometry to deliver a clean, powerful tone without the resonance that plagues lesser systems. The result is a raised-pitch, raucous howl at higher rpm and hard throttle, and a refined, near-stock character when you want to travel quietly.
The system runs two operating modes. With the valves open, gases flow completely freely through the X-pipe and a short resonator for the most aggressive sound and flow. With the valves closed, the gas is routed through four chambers and four resonated sections, bringing the volume down to near-stock levels for relaxed cruising and cold starts.
Inconel 625 is an aerospace-grade alloy with extreme tensile strength and thermo-chemical stability, able to withstand temperatures beyond 1800F. Its strength allows thinner walls and meaningful weight savings, making it the choice for owners who want the lightest, most exotic system. 304 stainless steel is the proven industry-standard option: strong, stable and more affordable, while still delivering the full Kline sound and flow benefits.
Yes. This system is engineered for both the 992.1 (2019-2024) and the later 992.2 Carrera range, covering Carrera, Carrera S, Carrera 4, Carrera 4S and Carrera GTS. It bolts to the factory mounting points and integrates with the car's valve control.
The freer-flowing X-pipe design and sport catalytic or competition downpipe options reduce back pressure versus the restrictive factory setup, supporting stronger high-rpm performance. Flat 6 Motorsports has dyno-verified gains on the 992 GTS with this system.
Will it drone on the highway?
No. Kline designs the system with proprietary acoustic packing and a four-chamber closed-valve path specifically to eliminate drone, so highway cruising stays comfortable.
Does it work with my car's exhaust button?
Yes. The Valvetronic system integrates with the factory exhaust valve control, so the OEM button and drive-mode logic open and close the valves.
Is it compatible with Porsche Sport Exhaust cars?
Yes. It works with cars fitted with Porsche Sport Exhaust (PSE) as well as the standard exhaust.
Which catalytic option should I pick?
Re-use OEM downpipes keep emissions hardware stock, 100 and 200 cell sport cats free up flow while retaining catalytic conversion, and competition downpipes are the freest-flowing option for track use.
Can I get carbon fiber tips?
Yes. Every configuration can be ordered with genuine Kline carbon fiber tips, or you can re-use your OEM tips.
