SKU: MK-SSXAU483
The Milltek Non-Resonated Cat-Back Exhaust System is engineered for direct factory fitment on the Audi A3 8V 2.0 TFSI Quattro sedan. This 3.00" (76.20mm) mandrel-bent T304L stainless steel system replaces the OEM cat-back with no modification required, using factory hangers and mounting points. Constructed from premium T304L stainless steel and hand-finished for durability, the non-resonated design eliminates the factory resonance chamber to deliver an engineered tone with fuller mid- and high-frequency character. The larger bore improves exhaust scavenging, supporting modest dyno gains in flow efficiency. Titanium trim options available for visual customization. Fitment Details • Direct replacement for OEM cat-back exhaust (post-catalyst to tailpipe) • Audi A3 8V 2.0 TFSI Quattro (sedan; US-spec models) • Uses factory hangers and mounting brackets • 3.00" mandrel-bent piping for optimized flow • Non-resonated configuration for track and closed-course use Every system is individually tested and hand-finished to OEM+ quality standards. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
