Milltek 80mm Non-Resonated Cat-Back Exhaust - Audi RS3 8Y - SSXAU967

The Milltek 80mm Non-Resonated Cat-Back Exhaust is engineered specifically for the Audi 8Y RS3 (2021+). This OPF/GPF-back system replaces the factory exhaust with a direct-fit T304L stainless steel design, delivering improved flow and engineered tone without modification required.

Constructed from hand-finished T304L stainless steel with 80mm (3.15") mandrel-bent piping, this non-resonated system eliminates the OEM resonance chamber for a more aggressive full-throttle character. Uses OEM hangers and hangers for seamless fitment. Available with polished or gloss black tip finishes.
