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 and pass through, which increases efficiency. When used with the Catalyst Bypass Pipe, significant power gains can be achieved without restriction on gas flow caused by a catalyst. 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 - Compatible with Catalyst Bypass Pipe for significant power gains - Manufactured in the UK - Distributed to more than 90 countries Specifications: - Pipe Diameter: 70.00 - Installation Time: 3 to 3.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - Large-bore Downpipe with Cat Bypass - MSVW455REP - Front Connecting Pipe to OE - MSVW473 Vehicle Compatibility: - Seat Ibiza Cupra 1.8TFSI (6P) 2016-2017 - Volkswagen Polo GTI 1.8 TSI 192PS (3 & 5 door) 2015-2018
