Milltek Resonated Cat-Back Exhaust - Audi C7.5 A6 3.0 TFSI - Brushed Titanium Tips - SSXAU1057

The Milltek Resonated Cat-Back Exhaust System is engineered for direct factory fitment on the Audi C7.5 A6 3.0 TFSI V6 (2016-2018). This mandrel-bent, T304L stainless steel system replaces the factory cat-back section with a 70mm (2.76") bore, delivering measurable exhaust flow improvement and refined sound character without modification to OEM hangers or mounting points.

Hand-finished T304L stainless construction resists thermal stress and corrosion. The resonated design fine-tunes the OEM resonance point to unlock a more pronounced, engineered tone while maintaining a refined, non-aggressive character. Brushed titanium trim options available. Direct bolt-on installation using existing factory attachment points-no cutting, welding, or fabrication required.
