Milltek 80mm Resonated Cat-Back Exhaust system for Audi S8 D5 (Long Wheel Base) V8. Direct factory replacement fitment with OEM hangers and mounting points; no modification required. Hand-finished T304L stainless steel construction with Cerakote Black tips.

This resonated configuration delivers refined full-throttle character while maintaining composure at cruise, engineered to eliminate OE resonance points without introducing drone.
