Description

Milltek Resonated Cat-Back Exhaust System for Audi B9 S4 and S5 (non-Sport Differential models). Direct factory fitment, 2.50" (63.50mm) mandrel-bent T304L stainless steel construction with quad GT-100 polished tips. Engineered to deliver enhanced exhaust flow and an OE+ tone signature.

Hand-finished T304L stainless steel throughout, using OEM hangers and factory mounting points for drop-in installation. The resonated chamber design fine-tunes the resonance point for a sportier note without excessive interior drone. Dyno-proven gains in exhaust scavenging efficiency across the 3.0L turbo V6 powerband.
