Milltek Non-Resonated Cat-Back Exhaust | Audi B7 A4 2.0 TFSI Quattro - GT Tips

Milltek Non-Resonated Cat-Back Exhaust System for Audi B7 A4 2.0 TFSI Quattro and DTM (manual models). This 2.50" mandrel-bent system replaces the factory cat-back in its entirety, delivering engineered tone character and measurable exhaust flow gains without resonance chambers.

Hand-finished T304L stainless steel construction with CNC-formed GT100 polished trim tips. Direct factory fitment using OEM hangers-no modification required. Non-resonated design eliminates stock muffler resonance points, unlocking the engine's full acoustic signature across the rev range.
