GRAIL Valve Exhaust System
suitable for Porsche 992 Turbo / Turbo S

When raw power meets technological precision, something special is born - like the Porsche 992 Turbo. The GRAIL Valve Exhaust System translates that concept acoustically onto the road: composed, deep, and full of character. Engineered to meet the unique thermal and acoustic demands of the turbocharged six-cylinder, crafted from premium 304L stainless steel, and fully ECE-compliant.

Highlights

• ECE type approval - no registration required in all participating ECE countries
• 304L stainless steel - corrosion-resistant, long-lasting, and high-temperature capable
• Developed in Germany - perfectly tuned to the turbocharged engine and stock configuration
• Sound enhancement within legal limits - a rich, full soundscape without exceeding threshold values
• Outside the test zones - a powerful flat-six sound with turbo character
• Flow-optimized pipe routing - for efficient exhaust flow under high loads
• CNC-machined components - permanently durable, maximally precise
• Acoustically tuned silencers - balanced sound without disruptive frequencies
• Model-dependent Valve integration - OEM Valve or custom solution - always perfectly tuned and road-legal
