Milltek Non-Resonated Cat-Back Exhaust System for Audi B7 A4 2.0 TFSI Quattro and DTM (manual models). Direct factory fitment using OEM hangers; no modification required. 2.50" (63.50mm) mandrel-bent T304L stainless steel construction with GT100 polished tips. This non-resonated design eliminates the OE resonance chamber, delivering a pronounced, engineered tone at full throttle while maintaining street-legal sound levels at part-load. Hand-finished stainless construction resists corrosion and thermal degradation. Dyno-proven gains in mid-range torque delivery across the 2.0 TFSI EA888 platform. Fitment • Audi B7 A4 2.0 TFSI Quattro • Audi B7 A4 2.0 TFSI DTM • Manual transmission models • Cat-back configuration (factory turbo and cat retained) Engineered in-house and decibel-tested to balance aggressive character with usability. T304L stainless resists salt corrosion and maintains finish over time-no ceramic coating required. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
