GRAIL Valve Exhaust System
suitable for SEAT Leon ST Cupra R 4Drive DSG (5F / 5F8) – an HJS

The SEAT Leon ST Cupra R 4Drive is the most uncompromising variant of the model range – limited-edition, all-wheel drive, and already noticeably more expressive straight from the factory. The GRAIL Valve Exhaust System taps directly into that character, adding a sound profile that matches the looks: deep, forceful, technically refined – and fully ECE-compliant.

Highlights

• ECE type-approved – no registration required in all ECE-participating countries
• 304L stainless steel – rust-free, long-lasting, and high-temperature resistant
• Developed in Germany – specifically tuned for the R rear end and the 4Drive platform
• Sound enhancement within legal limits – distinctive, without exceeding thresholds
• Flow-optimized pipe routing – for ideal exhaust dynamics under high load
• CNC-machined components – robust, maintenance-free and precise
• Acoustically tuned silencers – clear sound without disruptive resonances
• Model-dependent Valve integration – OEM Valve or custom solution – always perfectly tuned and fully compliant
