The GPF/OPF functions almost as a secondary catalyst, and this product offers the option to remove it, similar to a Decat system. This bypass deletes the GPF/OPF, removing it from the exhaust system to improve performance. All performance exhaust systems are designed for a wide range of vehicles. The research and development team works throughout the year to deliver solutions for performance exhaust requirements. All products are made in the UK and distributed to more than 90 countries worldwide. - Bypasses and deletes the GPF/OPF from the exhaust system - Designed for a wide range of vehicles - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 76.20 - Fitment Time: 1 to 1.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSFD264: Resonated GPF Bypass - MSFD265: Adaptor for OE Cat Back Vehicle Compatibility: - 2019 and later Ford Focus Mk4 ST 2.3-litre EcoBoost Estate/Wagon/Combi (OPF/GPF Equipped) - 2019 and later Ford Focus Mk4 ST 2.3-litre EcoBoost Hatch (OPF/GPF Equipped)
