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 the restriction caused by a catalyst. All Milltek Sport performance exhaust systems are developed for a wide range of vehicles and are manufactured in the UK. - Larger diameter than OEM downpipes for improved gas flow - Designed for increased efficiency and performance - Compatible with Catalyst Bypass Pipe for unrestricted gas flow - 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: - 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 - MSVW493REP: Non-Resonated Connecting Pipe Vehicle Compatibility: - 2018-2019 Volkswagen Polo GTI 2.0 TSI (AW - 5 Door) - Non GPF/OPF Models Only
