GRAIL Valve Exhaust System
suitable for BMW M3 F80 3-inch – OPF

The BMW M3 F80 with its S55 biturbo inline-six delivers a distinctive foundation for an intense driving experience. The GRAIL Valve Exhaust System in 3-inch specification complements that character with an audibly sporty, clearly defined sound profile and precision craftsmanship. Optionally, the equal-length variant can be ordered directly alongside it, achieving equal-length exhaust paths and making the sound even more harmonious.

• 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
