Milltek Non-Resonated Cat-Back Exhaust - Audi B9 S4 S5 - Polished Tips - SSXAU650

Milltek 2.50" (63.50mm) Non-Resonated Cat-Back Exhaust System for Audi B9 S4 and S5. Direct factory fitment for non-sport differential models; uses OEM hangers, no modification required. T304L stainless steel construction, hand-finished quad GT-100 polished trims.

Mandrel-bent 2.50" pipe diameter optimizes exhaust scavenging for the 3.0L turbo V6 (EA839). Non-resonated design eliminates mid-range resonance for a sharper, more aggressive tone at full throttle while maintaining street-legal operation. T304Lstainless resists thermal cycling and corrosion.
