Milltek Sport Large-Bore Downpipes are designed to improve both performance and sound. These downpipes feature a larger diameter compared to standard OEM parts, allowing more exhaust gas to exit the engine, which increases efficiency. When combined with the Hi-Flow Sports Cat, a significant increase in performance and a noticeable change in sound can be expected. All Milltek Sport performance exhaust systems are manufactured in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM for increased gas flow - Significant performance and sound improvements with Hi-Flow Sports Cat - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 70.00 - Fitment Time: 3 to 3.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSVW455: Large-bore downpipe and hi-flow sports catalyst (200CPSI) - MSVW455 - MSVW456: Front Connecting Pipe - MSVW456 Vehicle Compatibility: - Seat Ibiza Cupra 1.8TFSI (6P) 2016-2017 - Volkswagen Polo GTI 1.8 TSI 192PS (3 & 5 door) 2015-2018
