Milltek 80mm Non-Resonated Cat-Back Exhaust - Audi RS3 8V - Brushed Titanium Tips - SSXAU895

The Milltek 80mm Non-Resonated Cat-Back Exhaust is engineered specifically for the Audi 8V RS3, replacing the factory system with a direct-fit performance upgrade. Mandrel-bent T304L stainless steel construction delivers improved exhaust flow and a more aggressive sound character without resonance chambers.

Constructed from hand-finished T304L stainless steel-not standard T304L-this system uses OEM hangers for straightforward installation. The 80mm (3.15") bore optimizes scavenging while the non-resonated design accentuates full-throttle character and mid-range response. Available with titanium trim options.
