Large Bore Downpipe with 200 Cell High Flow Cat is designed to improve both performance and sound. The downpipe features 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 performance exhaust systems are made in the UK and distributed to over 90 countries. - Large diameter downpipe increases exhaust flow - Includes 200 cell high flow catalytic converter - Designed for improved performance and sound Specifications: - Pipe Diameter: 76.20 - Race Product: Yes - EMarked: No Kit comes with: - MSFD223: Large Bore Downpipe & Hiflow Cat - MSFD223 - MSFD224: Connecting Pipe to Milltek Sport Cat Back - MSFD224 Vehicle Compatibility: - 2016-2018 Ford Focus Mk3 RS 2.3-litre EcoBoost 4wd 5-Door Hatchback
