Description
The Milltek Resonated Cat-Back Exhaust System is engineered for the Audi B9 S5 3.0 V6 Turbo Coupe and Cabriolet (Non-Sport Diff models only). Direct factory fitment using OEM hangers and mounting points-no modifications required.
Hand-finished T304L stainless steel construction with mandrel-bent 2.50" (63.50mm) diameter piping. Resonated design eliminates drone while preserving full-throttle character, tuned to the EA839 engine's natural resonance points for an OE+ tone. Quad GT-100 polished trims with precision CNC-formed collectors. Uses factory valve compatibility where applicable.
