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 caused by a catalyst. All Milltek Sport performance exhaust systems are manufactured in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM downpipes for increased gas flow - Compatible with Catalyst Bypass Pipe for significant power gains - 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 - MSM350REP: Large-bore Downpipe and Decat - MSM350REP Vehicle Compatibility: - 2014-2018 Mini Mk3 (F56) Cooper S 2.0 Turbo (UK and European models, Pre-LCI only)
