Kline Innovation Adjustable Valvetronic Exhaust for Porsche 992 Turbo and Turbo S (2020–2024)

Description

The Kline Innovation Valvetronic Exhaust System for the 2020+ Porsche 911 Turbo / Turbo S (992) transforms the factory-exhaust feel into high-performance exotic status with full valved control. Featuring a lightweight Inconel X-pipe, bypass-capable silencers, and optional high-flow catalyst or de-cat downpipe configurations, this system delivers deeper tone, sharper response and a premier finish for serious Porsche owners. With stealth mode quiet at low opening and racetrack roar at full valve lift, it’s built to satisfy both daily-drive comfort and high-rev thrill.

Fitment Notes

• Fits 2020-on Porsche 911 Turbo / 911 Turbo S (992 chassis) 

• Multiple material and catalyst options (304 stainless / Inconel 625; 100-cell / 200-cell / competition / de-cat downpipes) – confirm selection matches application and local emissions regulations. 

• Valve electronics and integration: Ensure vehicle’s valve motor/switch system compatible or upgraded as required for valved system functionality.

• Street legality varies: Because the system offers de-cat options and high-flow components, emissions and noise compliance must be checked for your jurisdiction.

Included

• Complete valved rear exhaust system assembly for 992 Turbo / Turbo S, including X-pipe and bypass-capable silencers.

• Choice of down-pipe configuration per order: OEM reuse, 100-cell catalyst, 200-cell catalyst, or competition/de-cat variant. 

• Exhaust tips: Upgraded/pre-preg carbon fiber or OEM-style depending on selected tip finish.

• Mounting hardware, gaskets, valve actuation components (as applicable), and installation instructions.

Product Specs

• X-pipe diameter: 70 mm.

• Silencer transit diameter: 50 mm.

• Catalyst pipe diameter: 70 mm; overall catalyst cross section 122 mm (when applicable).

• Material weight examples: Rear silencer section in 304-grade stainless weighs approx 9.75 kg; Inconel 625 super-alloy version approx 6.95 kg.

• Performance potential: With de-cat and correct tune on this Turbo platform Kline indicates “over 40 hp and 55 Nm” gains from stock exhaust when paired with full system.

Product Features

• Valvetronic control – The system includes fully bypass-capable silencers so you can switch between stealth driving (valves closed) and aggressive track mode (valves open) with a remote or vehicle switch. 

• Exotic material construction – Options include F1-grade Inconel 625 or premium 304 stainless steel, enabling major weight savings, high heat resistance and premium finish.

• High-flow design – With fully internal routing at 70 mm diameter, optimized X-pipe and choice of down-pipe catalyst/de-cat configurations, flow is dramatically improved, increasing throttle response and mid-to-top-end power.

• Tone and presence – By replacing the heavy OEM rear silencer and optimizing side-walls and geometry, the exhaust tone shifts to a more exotic high-pitched scream under load yet remains manageable when valves are closed. 

• Customization options – From material selector (stainless vs Inconel), catalyst density (100-cell, 200-cell, competition/de-cat) and tip finish (OEM reuse vs carbon fiber), you build the system to match your driving style and aesthetic. 

• Built for dual purpose – Whether you’re seeking a refined street build or turning your 992 Turbo into a weekend track weapon, this system offers the flexibility, performance and sound to satisfy both worlds.
