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 restriction from a catalyst. All Milltek Sport performance exhaust systems are developed for a wide range of vehicles, with ongoing research and development to meet performance exhaust requirements. - Larger diameter than OEM for improved gas flow - Designed for increased efficiency and performance - Compatible with Catalyst Bypass Pipe for significant power gains Specifications: - Pipe Diameter: 76.20 - Race Product: Yes - EMarked: No Kit comes with: - Front Connecting Pipe - MSAU617 - Cast Large Bore Downpipe and Decat Pipe - MSVAG07 Vehicle Compatibility: - 2014-2020 Audi A3 2.0 TFSI quattro Sedan 8V (US-only) - 2013-2018 Audi S3 2.0 TFSI quattro 3-Door 8V/8V.2 (Non-GPF Equipped Models Only) - 2013-2018 Audi S3 2.0 TFSI quattro Saloon & Cabrio 8V/8V.2 (Non-GPF Equipped Models Only) - 2013-2018 Audi S3 2.0 TFSI quattro Sportback 8V/8V.2 (Non-GPF Equipped Models Only) - 2017-2018 Seat / Cupra Leon ST Cupra 300 (4x4) Estate / Station Wagon / Combi (Non-OPF/GPF)
