Milltek Sport Large-Bore Downpipes are designed to enhance both performance and sound. These downpipes feature a larger diameter compared to standard OEM parts, providing increased space for exhaust gases to exit the engine and pass through, which improves 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 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 worldwide 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: - F5152: Adapter to OE OPF Back 70 I.D. to 65 I.D. 90 long - MSVW491REP: Decat Downpipe - MSVW491REP - MSVW492REP: Non-Resonated OPF/GPF Bypass Pipe - MSVW492REP Vehicle Compatibility: - 2019-2021 Volkswagen Polo GTI 2.0 TSI (AW 5 Door PRE Facelift Models only) - GPF/OPF Models Only
