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 exhaust 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 - Designed for increased efficiency and performance - Noticeable difference in exhaust sound - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 76.20 - Race Product: Yes - EMarked: No Kit comes with: - MSFD146: 200 CPSI Hi-Flow Sports Catalyst (ECU remap required) - MSFD146 - MSFD145: Large-bore Downpipe - MSFD145 - F7056: Downpipe Mounting Bracket (Focus ST 225) Vehicle Compatibility: - 2005-2010 Ford Focus Mk2 ST 225
