The Milltek 70mm Resonated Cat-Back Exhaust System is engineered specifically for the Audi C7.5 A6 3.0 TFSI V6. This is a direct factory fitment cat-back system that replaces the OEM exhaust from the rear of the secondary catalytic converter rearward, using existing OEM hangers and mounting points with no modification required. Constructed from T304L stainless steel with mandrel-bent pipe work, the system features a resonated design tuned to the C7.5 A6's resonance points for an OE+ sound character-sportier and more refined than stock, without excessive drone. The 70mm (2.76") pipe diameter improves exhaust scavenging across the RPM range. Hand-finished tips and available carbon trim finishes deliver premium aesthetics.
