Milltek Non-Resonated Cat-Back Exhaust - Audi TT MK1 - Carbon Fibre Tips - SSXAU1041

The Milltek Non-Resonated Cat-Back Exhaust System is a direct factory fitment for the Audi TT MK1 V6 Quattro, replacing the OEM exhaust with a hand-finished T304L stainless steel system engineered for enhanced flow and aggressive tone character.

Constructed from premium T304L stainless steel with mandrel-bent piping at 2.76" (70.00mm) diameter, this non-resonated design eliminates the factory resonance chamber to deliver a pronounced, full-throttle note. The system uses OEM hangers and requires no modification for installation. Direct replacement fitment ensures immediate bolt-on compatibility with existing TT MK1 components.
