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 produced in the UK and distributed to over 90 countries. - Larger diameter than OEM for increased gas flow - Designed for improved performance and sound - Compatible with Catalyst Bypass Pipe for significant power gains - Manufactured in the UK and distributed worldwide Specifications: - Pipe Diameter: 76.20 - Fitment Time: 1.5 to 2 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSTY115: Adaptor to OE Downpipe - MSTY116: Resonated OPF Bypass Vehicle Compatibility: - 2020-2024 Toyota Yaris Gen 1 - GR & GR Circuit Pack 1.6T (OPF/GPF Models Only)
