GRAIL Valve Exhaust System.

The BMW M5 (G90/G99) combines an M Hybrid powertrain, where a 4.4-liter V8 twin-turbo engine and an electric motor work seamlessly together. The M xDrive all-wheel drive and four-wheel steering complete a package that offers exceptional performance on country roads, motorways, and racetracks alike. High system power, instantly available torque, and intelligent power distribution ensure powerful and controlled acceleration in all driving conditions.

The GRAIL Valve Exhaust System takes this package to a new level by adding clarity, depth, and emotion to the V8 engine's soundscape – without compromising the M5 models' excellent ride comfort.

Highlights

• Emphasizes the recognizable sound of the M Hybrid V8 engine, making it more powerful and immersive.
• Improves the soundscape of acceleration, especially when accelerating out of corners.
• Designed without distracting interior noise or low-frequency resonance (drone).
• Precisely aligned exhaust tips and model-specific piping fit perfectly into the wide rear of the BMW M5 Sedan and Touring models.
• ECE-approved – no separate inspection or registration required* in countries under ECE approval.
• Made from high-quality 304L stainless steel.
• CNC-machined precision parts ensure excellent durability and a perfect fit.
• Flow-optimized piping improves exhaust gas flow and effectively withstands high temperatures.
• Designed and developed by German engineers – first-class design and manufacturing quality.
