The Porsche 718 GTS 4.0L, Spyder and Spyder RS come with a valve-controlled OPF exhaust from the factory — one that quietly muffles an engine that deserves to be heard. The Cargraphic Exhaust Valve Controller is the simplest, most elegant fix: it opens those valves on demand, unlocking the natural sound of the 4.0-litre flat-six without any irreversible modification to the car.
No exhaust swap needed. No workshop time. Completely reversible. And at a fraction of the cost of a full aftermarket system, it's the first upgrade we recommend to every 718 GTS / Spyder owner who wants more sound from their car.
How it works
The factory exhaust uses electronically controlled bypass valves to reduce noise. The Cargraphic controller intercepts the factory signal and overrides the valve position — fully open when you want it, returning to standard operation when you don't. The controller comes with a remote handset or can be operated via the included switch modes depending on the option chosen.
Options
2 Modes: Open / Closed — simple, clean, immediate. The valve is either open or in factory position. Best for owners who want a clear on/off choice. £330.
3 Modes: Open / Closed / Auto — adds an automatic mode that opens the valves at higher throttle/RPM and closes them in gentle driving. Best for owners who want maximum versatility without manually switching. £429.
Not compatible with 718 models fitted with the 2.0T or 2.5T four-cylinder engine — those use a different exhaust valve system. Contact us if you're unsure of your model specification.
Installation
Fitting is straightforward and can typically be completed in under an hour without specialist tools. Full instructions included. Fitting available at our UK premises if preferred.
