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 70mm T304L stainless steel system replaces the factory cat-back, delivering improved exhaust flow, measurable performance gains, and a refined OE+ sound character without resonance drone. Hand-finished T304L stainless construction with mandrel-bent piping ensures precision fitment and longevity. The resonated design targets the factory resonance point, eliminating highway drone while amplifying full-throttle tone. Direct OEM hangers and factory-compatible mounting brackets mean zero modification required. Cerakote Black trim tips provide a premium visual upgrade that complements modern Audi styling.
