GRAIL Valve Exhaust System
suitable for BMW M3 G8x

In a nutshell

Sound check

The BMW M3 G8x stands for uncompromising driving dynamics and pure M performance – whether as the G80 Saloon or G81 Touring. Its 3.0-litre twin-turbocharged inline-six provides a characterful foundation that the GRAIL Valve Exhaust System builds on consistently. It gives the S58 engine greater expression, making every rev range audibly more alive without compromising everyday comfort. Precision-crafted, cleanly integrated, and acoustically fine-tuned.

Highlights

• Characterful straight-six sound – audibly sporty in character, with a punchy, assertive feel under acceleration.
• Perfect integration and striking Tip design – emphasises the M aesthetic and rounds off the rear styling harmoniously.
• ECE type-approved – no registration required* in all participating ECE countries
• Crafted from high-quality 304L stainless steel
• CNC-machined precision parts – maximum durability and perfect dimensional accuracy
• Flow-optimized pipe routing – optimal exhaust flow and temperature stability
• Developed by German engineers – the highest precision in design and manufacturing
