GRAIL Valve Exhaust System
suitable for BMW M850i G1x – 11/2020–03/2024 (LCi 1) G14 (Convertible)

The BMW M850i is the essence of the Luxury GT – its 4.4-litre V8 biturbo combines effortless power with the refinement of a true Gran Turismo icon. Our GRAIL Valve Exhaust System gives the 8 Series the sonic character that the stock system only hints at: powerful, present, and with a composure that does justice to the presence of this car.

Highlights

• Distinctive V8 twin-turbo sound – commanding, powerful, and with the presence that defines the 8 Series
• A clearly noticeable difference from the stock system – from subtle and comfortable to impressively present
• For all G1x generations – Pre-LCi, LCi 1 and LCi 2 in Coupé, Cabriolet and Gran Coupé
• ECE type approval: No registration required* in all participating ECE countries.
• German Engineering: Developed by German engineers for maximum quality.
• Premium Material: Crafted from high-quality 304L stainless steel with a flawless surface finish.
• Flow-optimized: Efficient exhaust pipe routing and heat dissipation.
• Drone-free comfort: Absorption technology eliminates unwanted frequencies inside the cabin.
• OEM fit: Designed to mount at the original mounting points.

This exhaust system holds an ECE type approval and is therefore approved for road use with no registration required*.

*Applies to vehicles with EU registration in stock condition. For imported vehicles, or in combination with further modifications (e.g. power upgrades, intake), a separate inspection and approval may be required. Please get in touch with our support team: [email protected]
