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 from a catalyst. All Milltek Sport performance exhaust systems are made in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM for increased gas flow - Designed for improved performance and sound - Compatible with Catalyst Bypass Pipe for significant power gains - Made in the UK and distributed globally Specifications: - Pipe Diameter: 70.00 - Fitment Time: 2.5 to 3.5 hours (including removing 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 - 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
