GRAIL Valved Exhaust System | ECE | suitable for BMW M5 F10 Sedan

GRAIL Valve Exhaust System
suitable for BMW M5 F10

The BMW M5 F10 puts 560 PS from a 4.4-litre V8 biturbo onto the road - a real statement under full load, yet acoustically restrained as standard. The GRAIL Valve Exhaust System takes the sonic potential of this engine to a whole new level: powerful, raw and technically tuned to the character of the S63. Precision-crafted from 304L stainless steel and fully ECE-compliant - for uncompromising sound enjoyment with road approval.

Highlights

• ECE type approval - no registration required in all participating ECE countries
• 304L stainless steel - temperature-resistant, durable, rust-free
• Developed in Germany - perfectly tuned for the M5 platform and V8 biturbo
• Sound-optimized within legal limits - maximum sound within the permitted range
• Outside the test zones - full biturbo sound with goosebump potential
• Flow-optimized pipe routing - for balanced pressure conditions and ideal thermodynamics
• CNC-machined components - precise fit, durable and low-maintenance
• Acoustically tuned silencers - clear sound without disruptive frequencies
• Model-dependent Valve integration - OEM Valve or custom solution - always perfectly tuned and road-legal
