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 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 increase in performance with Hi-Flow Sports Cat - Noticeable difference in exhaust sound - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 63.50 - Race Product: Yes - EMarked: No Kit comes with: - Large-bore Downpipe and Hi-flow Sports Catalyst - MSM321 Vehicle Compatibility: - 2006-2014 New Mini Mk2 (R56) Cooper S 1.6i Turbo - 2011-2015 New Mini Mk2 (R58) Cooper S Coupe
