GRAIL Valved Exhaust System | ECE | suitable for Audi S4 (B8/B8.5) | Vor-facelift (B8) Avant

GRAIL Valve Exhaust System
suitable for Audi S4 B8 / B8.5 – Vor-facelift (B8) Avant

The Audi S4 of the B8 and B8.5 generations combines a composed presence with the distinctive dynamics of the 3.0-litre TFSI supercharged V6. The GRAIL Valve Exhaust System sharpens this character with an audibly sporty edge, bringing the powertrain's forceful nature more clearly to the fore. Our design integrates precisely into both model variants and remains perfectly tailored to the S4 in terms of dimensions and materials.

Highlights

• The 3.0-litre TFSI supercharged V6 gains an audibly sporty, forceful sound character through the GRAIL Valve Exhaust System – precisely tuned for both model generations.
• Precision-developed for the Avant and Saloon: the Tips sit flush with the rear apron and accentuate the S4’s sporty lines.
• 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
