GRAIL Valve Exhaust System
suitable for Ford Mustang VI (S550) 2.3 EcoBoost US Model

The US-spec Mustang VI with the 2.3-litre EcoBoost relies on an efficiently engineered turbocharged engine and a driver-focused setup precisely tailored for everyday use and spirited road driving. The lightweight four-cylinder pairs harmoniously with the well-balanced chassis, delivering direct throttle response across the entire rev range. The GRAIL Valve Exhaust System builds on this technical foundation, shaping a clearly defined, sporty sound character that consistently complements the EcoBoost’s personality.

• 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
• Flow-optimized pipe routing – optimal exhaust flow and temperature stability
• Developed by German engineers – the highest precision in design and manufacturing
