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 from a catalyst. All Milltek Sport performance exhaust systems are made in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM for increased gas flow - Designed for improved performance and sound - Compatible with Catalyst Bypass Pipe for significant power gains Specifications: - Pipe Diameter: 70.00 - Installation Time: 2 to 2.5 hours (including removing OE system) - Fitting Notes: O.E system requires cutting for removal - Race Product: Yes Kit comes with: - Large-bore Downpipe and Decat - MSSE132REP - Flex Connecting Pipe - MSSE133 Vehicle Compatibility: - 2010-2015 Audi A1 1.4 TFSI S line 185PS S tronic - 2009-2015 Seat Ibiza Cupra / Bocanegra 1.4 TSI 180PS
