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 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 improved gas flow - Significant performance and sound enhancement with Hi-Flow Sports Cat - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 76.20 - Fitment Time: 1 to 1.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSVW257: Large-bore downpipe and hi-flow sports catalyst - MSVW257 - MSVW383: 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
