Milltek Non-Resonated Cat-Back Exhaust - Audi B6 A4 1.8T Quattro - 90mm Jet Tips - SSXAU307

The Milltek Non-Resonated Cat-Back Exhaust System is engineered for direct factory fitment on the Audi B6 A4 1.8T Quattro (all body styles including Cabriolet). This 2.50" mandrel-bent T304L stainless steel system replaces the OEM cat-back section, delivering dyno-proven flow gains and engineered tone character without resonance chambers.

Hand-finished T304L stainless construction resists corrosion and thermal stress. The non-resonated design eliminates OE resonance points, producing a sportier exhaust note at full throttle while maintaining OEM+ fitment through existing hangers. 90mm polished trim options available. No modification required-direct bolt-on replacement using factory mounting points.
