GRAIL Valve Exhaust System + GRAIL Downpipe
suitable for BMW M3/M4 G8x PACKAGE

The BMW M3 G80 saloon stands for uncompromising driving dynamics and pure M performance. Its 3.0-litre straight-six S58 twin-turbo lays the foundation for a driving experience that the GRAIL package sharpens to perfection: the GRAIL Valve Exhaust System and the GRAIL Downpipe work together as a harmonious overall system that precisely combines sound, pull and thermal efficiency. Both components carry their own ECE type approval, making them no registration required* in all participating ECE countries.

Highlights

• Characterful straight-six sound – audibly sporty in character, with a forceful surge under acceleration
• GRAIL Downpipe with High-Flow Catalyst – optimized exhaust routing and temperature resistance
• Both components 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 dimensional accuracy
• Flow-optimized pipe routing – efficient exhaust flow and thermal stability
• Developed by German engineers – precise integration on the S58 engine
