Milltek Downpipe 3" Downpipe with High Flow Catalytic Converter - Volkswagen MK7.5 GTI

Description Milltek Sport Large-Bore Downpipes are perfect when looking to improve both performance and sound. These downpipes are fabricated with a larger diameter than standard OEM parts, meaning that there is significantly more space for more gas to exit the engine and pass through, increasing efficiency. Combined with our Hi-Flow Sports Cat, you can expect a significant increase in performance and a noticeable difference in sound aesthetic. Stage 2 ECU Remap Required. For OE Cat-back System Only Stage 2 ECU Remap Required for Maximum Performance.
