Milltek 80mm Resonated Cat-Back Exhaust - Audi TTRS MK3 - Polished Tips - SSXAU961

The Milltek 80mm Resonated Cat-Back Exhaust System is engineered as a direct factory fitment for the Audi TTRS MK3 Quattro. This system replaces the OEM cat-back section, delivering improved exhaust flow through mandrel-bent T304L stainless steel tubing while preserving a refined, OE+ sound character via integrated resonance chambers.

Constructed from T304L stainless steel (durability) and hand-finished to Milltek standards, the system uses OEM hangers and requires no modification for installation. The 80mm (3.15") bore diameter maximizes flow efficiency. Polished trim options are available to match your finish preference. This resonated configuration eliminates drone while maintaining the sporty exhaust note expected from a TTRS platform.
