Seat Ibiza Cupra 1.8 TFSI & VW Polo GTI 1.8 TSI - Large Bore Downpipe with Hi-Flow Sports Catalyst (For Milltek Cat-Back) - Milltek Cat-Back

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.
