MagnaFlow NEO Series Cat-Back Exhaust for 2023+ GR Corolla 1.6L - 19631

Transform the sound, appearance, and performance of your 2023+ Toyota GR Corolla 1.6L with the MagnaFlow NEO Series Cat-Back Performance Exhaust System #19631. Engineered specifically for the turbocharged GR Corolla, this direct-fit exhaust combines 3-inch mandrel-bent stainless steel piping with a tuned NDT chamber, smooth-flowing Y-pipe, and dual straight-through performance mufflers for a freer-flowing exhaust path and MagnaFlow’s modern performance sound. Integrated No Drone Technology helps reduce unwanted resonance during steady-speed cruising, while MagnaFlow’s cast 304 stainless steel actuated valve retains compatibility with the factory controllable exhaust system. A distinctive quad center-exit layout finishes the system with black chrome, double-wall angle-cut tips in staggered 4.5-inch outer and 3.5-inch inner diameters. Built from corrosion-resistant stainless steel using precision CNC robotic manufacturing, the NEO Series #19631 delivers aggressive styling, responsive sound, and dyno-proven performance while maintaining everyday drivability.
