The Milltek Resonated Cat-Back Exhaust System is engineered specifically for the Audi MK3 TTS, replacing the factory setup with hand-finished T304L stainless steel construction. This system delivers direct factory fitment using OEM hangers with no modification required. Built from T304L stainless steel with mandrel-bent 3.00" (76.20mm) piping, the resonated design fine-tunes the OEM resonance point to eliminate drone while preserving a full-throttle character that's sportier than stock. Cerakote Black oval tips provide premium aesthetics that integrate seamlessly with the OE+ fitment philosophy.
