Milltek Resonated Cat-Back Exhaust - Audi B9 A4 2.0 TFSI Quattro - Burnt Titanium Tips - SSXAU610

The Milltek Resonated Cat-Back Exhaust System is engineered for direct factory fitment on Audi B9 A4 2.0 TFSI Quattro Saloon and Avant models. This 2.75" (70mm) mandrel-bent T304L stainless steel system replaces the stock exhaust with no modification required, using OEM hangers and factory mounting points.

Hand-finished T304L stainless construction resists corrosion and delivers lasting durability. The resonated design fine-tunes the OEM resonance point to eliminate drone while preserving the stock exhaust character-a true OEM+ tone that sounds purposeful without aggression. Direct bolt-on fitment takes 2-3 hours for a professional installer.
