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 increased gas flow - Designed to enhance both performance and sound - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 69.85 - Race Product: Yes - EMarked: No Kit comes with: - F5134: Sleeved Downpipe Adapter 70 O.D. to 70 I.D. 105 long - MSM350: Large-bore Downpipe and Hi-Flow Sports Catalyst - MSM350 Vehicle Compatibility: - 2014-2018 Mini Cooper S 2.0 Turbo (F56, UK and European models, Pre-LCI Only)
