Description

Milltek Resonated Cat-Back Exhaust System for Audi D4 S8 Quattro. Direct factory fitment cat-back system engineered to replace the OEM exhaust with improved flow dynamics and refined sound character. Mandrel-bent T304L stainless steel construction with hand-finished titanium trim options.

The resonated design eliminates drone at cruise while preserving full-throttle character on hard acceleration. 2.76" (70mm) bore optimizes scavenging for the D4 platform's naturally aspirated engine. Uses OEM hangers and mounting points-no modification required. CNC-formed junctions and precision welding throughout.
