3-Inch Large Bore Downpipe and Hi-Flow Sports Cat

The Milltek SSXTY154 is a performance-oriented large bore downpipe and hi-flow sports cat engineered for the Toyota Corolla GR Corolla 1.6 Turbo from 2023 to 2027. This system features a 3-inch (76.2mm) diameter, mandrel-bent for consistent radius bends and optimized gas flow. It includes a 200CPSI catalyst and is intended to fit with Milltek Sport secondary cat-back systems, while also accommodating the OE secondary cat position. It is crucial to note that this is a race system and is not ECA approved, meaning it will inhibit your vehicle from passing a MOT test and is intended for off-road/motorsport use only. Furthermore, installation of this downpipe requires Stage 2 ECU software.
