Overview

The Milltek Resonated Cat-Back Exhaust System is a direct factory replacement for the Audi B9 S4 and S5, engineered to enhance exhaust flow and refine the OE+ sound character without aggressive resonance. This system uses 2.50" (63.50mm) mandrel-bent T304L stainless steel throughout, hand-finished for durability and corrosion resistance.

Installation requires no modification - the system uses OEM hangers and integrates seamlessly with factory components. The resonated design tuned to eliminate drone at cruising speeds while delivering a more pronounced full-throttle note. Quad GT-90 burnt titanium trims are included as standard.
