The GPF/OPF functions almost as a secondary catalyst, and this product provides the option to remove it, similar to a Decat system. The bypass deletes the GPF/OPF, removing it from the exhaust system to improve performance. All performance exhaust systems are designed to cater to 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 over 90 countries worldwide. - Deletes the GPF/OPF from the exhaust system - Designed for improved performance - Made in the UK - Distributed to more than 90 countries Specifications: - Pipe Diameter: 76.20 - Race Product: Yes - EMarked: No Kit comes with: - GPF/OPF Bypass Pipe (Non-Resonated) - MSMZ104REP - Adaptor to OE System - MSMZ105 Vehicle Compatibility: - 2019 and later Mercedes A-Class A35 AMG 2.0 Turbo (Saloon/Sedan Only - OPF/GPF Models) - 2019 and later Mercedes A-Class A35 AMG 2.0 Turbo (W177 Hatch Only OPF/GPF Models) - 2019 and later Mercedes CLA-Class CLA35 AMG 2.0 Turbo Coupe & Shooting Brake (OPF/GPF Models)
