Porsche 911 GT3 RS (992) – GRAIL Exhaust - Valved Exhaust System

The Porsche 911 GT3 RS (992) represents the pinnacle of performance – and the GRAIL valved exhaust system brings this character to life acoustically. The result is an uncompromisingly powerful, technically precise, and fully type-approved legal soundscape.

The naturally aspirated 4.0-liter boxer engine thrives on revs, responsiveness, and emotion. The GRAIL exhaust system emphasizes this with a deep, motorsport-inspired sound profile – wherever it's permitted. Developed in Germany and crafted from L304 stainless steel, the system is optimized for both track days and road use.

Highlights

• ECE type-approved – registration-free in all countries recognizing ECE approval

• L304 stainless steel – high-quality, durable, and motorsport-tested

• Developed in Germany – designed for maximum durability and perfect compatibility

• Sound optimization within legal limits – full performance within permissible boundaries

• Maximum sound development outside test areas – GT3 RS in its purest form: sharp, loud, and emotional

• Flow-optimized exhaust gas management – efficient gas exchange under high load

• CNC-machined flap components – durable, precise, and reliable construction

• Acoustically tuned mufflers – authentic motorsport character without compromises

• Model-specific flap integration* – standard or special solution, always optimally adapted and compliant with regulations

Technical Refinement – Perfectly Integrated

The exhaust flap control is finely tuned specifically for the vehicle – regardless of whether original components or separate solutions are used. The result always meets legal requirements and offers an optimal combination of sound, functionality, and usability on both track and road.

If you are unsure about your system or the specific requirements of your vehicle, we recommend contacting an expert before purchasing.

Designed for the driver who demands everything from their Porsche 911 GT3 RS (992) – maximum performance, raw motorsport sound, and perfect technical refinement.
