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. Note: Not compatible with vehicles which have an additional sensor straight off the turbo and the larger turbo flange. - Larger diameter than OEM for increased gas flow - Designed to improve performance and sound - Compatible with Catalyst Bypass Pipe for significant power gains Specifications: - Pipe Diameter: 76.20 - Race Product: Yes - EMarked: No Kit comes with: - MSVAG11: Cast Large-bore Downpipe and Decat Pipe - MSVAG11 - 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+ 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)
