Description

The Milltek 80mm Resonated Cat-Back Exhaust is engineered specifically for the Audi 8V RS3 (2017+). This T304L stainless steel system replaces the factory cat-back in its entirety, delivering improved exhaust flow, dyno-proven performance gains, and an engineered OE+ tone character with Cerakote black trims. Constructed from hand-finished T304L stainless steel with an 80mm (3.15") mandrel-bent primary pipe, the resonated design eliminates excessive drone while preserving a pronounced exhaust note at full throttle. Direct factory fitment-uses OEM hangers and mounting points, no modifications required. Finished in Cerakote black for durability and visual refinement.
