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 meet a wide range of vehicle requirements, with ongoing research and development to deliver in-demand solutions. All products are manufactured in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM for improved gas flow - Compatible with Catalyst Bypass Pipe for increased power - Manufactured in the UK and distributed globally - Designed for a wide range of vehicles Specifications: - Pipe Diameter: 70.00 - Installation Time: 2.5 to 3.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - F5151: Adapter to Milltek Sport OPF/Cat Back Systems 70 O.D. to 70 I.D. 130 long - MSVW491: Cast Downpipe with 200CPSI Hi Flow Sports Cat - MSVW491 - MSVW493: Resonated Connecting Pipe - MSVW493 Vehicle Compatibility: - 2018-2019 Volkswagen Polo GTI 2.0 TSI (AW - 5 Door) - Non GPF/OPF Models Only
