The Mercedes-AMG GT 63 and GT 63 S (X290) embody the idea of everyday driving performance: a four-door coupé powered by the uncompromising force of a V8 biturbo. With the GRAIL Valve Exhaust System, that character is made audibly sharper – a clearly defined, sporting sound signature underscores the drivetrain’s dynamics without compromising long-distance comfort.

Highlights

• V8 biturbo with spontaneous power delivery – GRAIL amplifies the characteristic AMG sound: forceful and drone-free
• Four-door coupé with performance DNA – GRAIL accentuates the dynamic sound signature during load changes and at high revs
• 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
