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 developed for a wide range of vehicles, with ongoing research and development to meet performance exhaust requirements. - 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: 76.20 - Installation Time: 1.5 to 2 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSTY117: OPF Bypass and 200 CPSI Catalyst - MSTY115: Adaptor to OE Downpipe Vehicle Compatibility: - 2020-2024 Toyota Yaris Gen 1 - GR & GR Circuit Pack 1.6T (OPF/GPF Models Only)
