The GPF/OPF functions almost as a secondary catalyst, and this product provides the option to remove it, similar to a Decat system. This bypass eliminates the GPF/OPF 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 manufactured in the UK and distributed to over 90 countries worldwide. - Bypass 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 - Installation Time: 2 to 3 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - F7096: Chassis Brace Plate - MSBM358: LH OPF/GPF Bypass - MSBM359: RH OPF/GPF Bypass - MSBM360: Centre Silencer - F5160: Adapter to Milltek Sport System Vehicle Compatibility: - 2020 and later BMW 3 Series G80/G81 M3 & M3 Competition S58 3.0 Turbo (OPF/GPF Equipped Cars Only) including Touring & XDrive Models - 2020 and later BMW 4 Series G82 M4 & M4 Competition S58 3.0 Turbo (OPF/GPF Equipped Cars Only)
