GRAIL Valve Exhaust System
suitable for Porsche 992 Carrera 4S

The 992 Carrera 4S strikes a sporting balance between performance, traction and everyday usability. The GRAIL Valve Exhaust System underscores this ambition with a sound profile that isn't loud for its own sake, but technically tuned – present, deep and clearly defined. Manufactured from high-quality 304L stainless steel, developed in Germany and consistently tailored to the acoustic and thermal demands of the six-cylinder engine.

Highlights

• ECE type approval - no registration required in all participating ECE countries
• 304L stainless steel – durable, corrosion-resistant, temperature-stable
• Developed in Germany – vehicle-specifically engineered for maximum fitment precision
• Sound optimisation within legal limits – tuned to the maximum permissible volume
• Outside the test zones – powerful flat-six sound with an emotional character
• Flow-optimized pipe routing – for effective exhaust flow and thermal stability
