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 from a catalyst. All Milltek Sport performance exhaust systems are manufactured in the UK and distributed to over 90 countries. - 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 worldwide Specifications: - Pipe Diameter: 76.20 - Race Product: Yes - EMarked: No Kit comes with: - MSFD146REP: Catalyst Replacement Pipe (ECU remap required) - MSFD146REP - MSFD145: Large-bore Downpipe - MSFD145 - F7056: Downpipe Mounting Bracket (Focus ST 225) Vehicle Compatibility: - 2005-2010 Ford Focus Mk2 ST 225
