These downpipes feature a larger diameter than standard OEM parts, allowing more exhaust gas to exit the engine and pass through, which increases efficiency. When combined with the Hi-Flow Sports Cat, a significant increase in performance and a noticeable change in sound can be expected. 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 to increase efficiency and enhance sound - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 76.20 - Race Product: Yes - EMarked: No Kit comes with: - MSVAG09: Cast Large Bore Downpipe 200cell HJS Catalyst - MSVAG09 - MSVAG12: Milltek Downpipe-to-OE Cat Back Connecting Pipe - MSVAG12 Vehicle Compatibility: - 2019-2020 Audi S3 2.0 TFSI quattro 3-Door 8V.2 (GPF Equipped Models Only) - 2019-2020 Audi S3 2.0 TFSI quattro Saloon & Cabrio 8V.2 (GPF Equipped Models Only) - 2019-2020 Audi S3 2.0 TFSI quattro Sportback 8V.2 (GPF Equipped Models Only) - 2019 and later Seat / Cupra Ateca Cupra 300 4Drive (GPF/OPF EA888 Gen3 Models Only) - Pre-facelift - 2019-2020 Seat / Cupra Leon ST Cupra 300 (4x4) Estate / Station Wagon / Combi (OPF/GPF Equipped Only)
