Milltek Sport Large-Bore Downpipes are designed to enhance 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 from a catalyst. All Milltek Sport performance exhaust systems are developed to suit a wide range of vehicles, with ongoing research and development to meet performance exhaust requirements. All products are manufactured in the UK and distributed to over 90 countries. - Larger diameter than OEM for improved gas flow - Compatible with Catalyst Bypass Pipe for increased power - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 70.00 - Installation Time: 2.5 to 3.5 hours (including removal of OE system) - Race Product: Yes - EMarked: No Kit comes with: - F5153: Adapter to OE Cat Back 70 I.D. to 60 I.D. 90 long - MSVW491REP: Decat Downpipe - MSVW491REP - MSVW493REP: Non-Resonated Connecting Pipe Vehicle Compatibility: - 2018-2019 Volkswagen Polo GTI 2.0 TSI (AW - 5 Door) - Non GPF/OPF Models Only
