Milltek 80MM Race Cat-Back Exhaust - Audi RS3 8V - Polished Tips - SSXAU983

The Milltek 80MM Race Non-Resonated Cat-Back Exhaust is engineered specifically for the Audi RS3 8V (2017+) as a direct factory replacement. This is our loudest cat-back option, featuring a 3.15" (80mm) mandrel-bent T304L stainless steel construction with race-spec rear silencer for maximum volume and reduced weight.

Hand-finished T304L stainless steel construction resists corrosion and delivers durability. The non-resonated design eliminates factory resonance chambers for full-throttle aggression, making this system ideal for closed-course and track applications. Direct OEM fitment uses factory hangers and mounting points-no modification required. Race-spec silencer delivers the most aggressive exhaust note in the Milltek cat-back lineup.
