Milltek 80MM Race Non-Resonated Cat-Back - Audi 8V RS3 - Brushed Titanium Tips - SSXAU984

The Milltek 80MM Race Non-Resonated Cat-Back Exhaust is engineered specifically for Audi 8V RS3 (2017+). This direct factory fitment system replaces the OEM exhaust with a larger 3.15" (80mm) mandrel-bent T304L stainless steel design, delivering maximum exhaust flow and the most aggressive sound character in the Milltek lineup.

Constructed from T304L stainless steel with hand-finished titanium trim options, this non-resonated system includes a race-spec rear silencer optimized for reduced weight and full-throttle acoustic intensity. Direct OEM hanger compatibility ensures installation without modification. The larger bore diameter facilitates improved gas scavenging and measurable performance gains on tuned applications.
