Milltek 80mm Non-Resonated Cat-Back Exhaust - Audi RS6 C8 - Polished Tips - SSXAU862

Milltek Non-Resonated & Valved Cat-Back Exhaust system for Audi C8 RS6 (2020+) and RS7 (2019+). Direct factory fitment with OEM hangers and valve integration. Twin 80mm (3.15") mandrel-bent T304L stainless steel construction with hand-finished polished oval trims.

This front silencer back system replaces the factory cat-back section while retaining OEM turbochargers and primary cats. The non-resonated design eliminates the factory resonance chamber for a sharper, more direct exhaust character at full throttle. Integrated electronic valve allows quiet cruising with full open-throttle soundtrack engagement. Direct bolt-on installation requires no modification to OEM hangers or mounting points.
