GRAIL Valve Exhaust System
suitable for BMW M5 (G90/G99) – Sedan (G90) Straight-Pipe

The BMW M5 (G90/G99) combines an M Hybrid system of V8 biturbo and electric motor, M xDrive and rear-wheel steering into a high-performance platform for saloon and Touring. High system output, instantly available torque and the variable distribution of drive forces deliver tangible thrust on the motorway, country road and circuit alike. The GRAIL Valve Exhaust System takes this concept further, making the V8 sound clearer, more characterful and simply more emotional – without compromising the long-distance comfort of the M5 models.

Highlights

• In the BMW M5 (G90/G99), the GRAIL Valve Exhaust System sharpens the sound of the M Hybrid V8, accentuates the surge when accelerating out of corners, and remains consistently free of drone.
• Precisely aligned Tips and a pipe routing tailored to both the Saloon and Touring integrate seamlessly into the wide M5 rear end, enhancing the presence of both vehicles.
• 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
