Milltek non-resonated cat-back exhaust system for Toyota GR Corolla 1.6 Turbo (2023+). Direct factory fitment replacement using OEM hangers and mounting points-no modification required. T304L stainless steel construction with mandrel-bent piping and hand-finished polished GT tips. This configuration is louder than resonated alternatives, engineered for full-throttle character and aggressive tone on track and closed-course driving. Hand-finished T304L stainless steel resists corrosion and thermal stress. Non-resonated design eliminates factory resonance chambers, maximizing engine note and minimizing restriction. Polished GT tips deliver aesthetic finish. Designed as a direct replacement for the OEM cat-back system-valved compatibility maintained where applicable. All Milltek systems undergo dyno testing and are EC type approved for engineering integrity. • Fits 6-speed manual transmission models only, not the 8-speed automatic (GR-DAT) • T304L stainless steel, mandrel-bent construction • Non-resonated for maximum engine tone and performance character • Hand-finished polished GT tips • Direct OEM+ fitment-uses factory hangers and mounting points • Suitable for track use and closed-course driving Milltek pioneered performance exhaust engineering in 1983.
