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 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 manufactured in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM for increased exhaust flow - Designed to enhance both performance and sound - Manufactured in the UK and distributed globally - Compatible with Hi-Flow Sports Cat for further gains Specifications: - Pipe Diameter: 76.20 - Race Product: No - EMarked: Yes - EMark Number: ecedownpipe Kit comes with: - Large-bore Downpipe and 200-CPSI Hi-flow Sports Catalyst (EC-Approved) - MSAU623 - Milltek Downpipe-to-OE Cat-back Connecting Pipe - MSVW439 Vehicle Compatibility: - 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)
