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 caused by a catalyst. All Milltek Sport performance exhaust systems are manufactured in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM downpipes for improved gas flow - Designed for increased efficiency and performance - Compatible with Catalyst Bypass Pipe for significant power gains - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 76.20 mm - Installation Time: 1 to 1.5 hours (including removal of OE system) - Race Product: Yes - EMarked: No Kit comes with: - Large-bore downpipe and catalyst replacement pipe - MSVW257REP - Adapter Milltek Catback to OE Downpipe - MSVW383 Vehicle Compatibility: - Audi A3 1.8T 2WD 3 & 5 door 1996-2004 - Seat Leon 1.8T Sport and Cupra 180PS 2000-2005
