The Milltek Resonated Cat-Back Exhaust is engineered for the Audi B9 RS5 Coupe and Sportback (2018-2019, non-GPF models). This direct factory replacement uses T304L stainless steel mandrel-bent piping with OEM+ fitment, no modification required. Constructed from premium T304Lstainless steel with hand-finished Cerakote black oval trims. The 2.76" (70mm) large bore diameter optimizes exhaust scavenging for measurable mid-range torque gains. Resonated design fine-tunes the OEM resonance point, delivering an engineered tone-refined under full throttle, compliant at cruise-rather than aggressive character. Fitment • Audi B9 RS5 Coupe (2018-2019, non-GPF) • Audi B9 RS5 Sportback (2018-2019, non-GPF) • Audi B9 RS4 Avant (2018-2019, non-GPF) Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
