Milltek Non-Resonated Cat-Back Exhaust System for Audi 8V RS3 (2017+). Direct factory fitment replacement engineered to eliminate resonance points and deliver a full-throttle character that rivals track-focused setups. 3" (76.20mm) mandrel-bent T304L stainless steel construction with hand-finished burnt titanium oval tips. This system uses OEM hangers and requires no modification for installation. T304L stainless steel resists corrosion and thermal cycling. The non-resonated design removes the OE silencer chamber, allowing unfiltered exhaust note development across the entire RPM band. Dyno-tested for measurable flow improvement over factory setup. Fitment • Audi RS3 8V (2017 and later) • Cat-back configuration (turbo-back not included) • Direct OEM+ fitment - no cutting, welding, or bracket modification • Compatible with OEM trim panels and undertray This non-resonated system is engineered for closed-course and enthusiast driving; verify local noise ordinances before street use. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
