Designed for customers planning to upgrade to a turbo back system in the future. From late 2018, many vehicles have been equipped with a Gasoline/Otto Particulate Filter to further reduce emissions. The Milltek Sport Particulate Filter-Back range is engineered to compensate for the sound-reducing qualities of the particulate filter and significantly enhance the exhaust system's sound aesthetic. All performance exhaust systems are developed to cater to a wide range of vehicles. Continuous evolution is a priority, with the research and development team working year-round to deliver solutions for performance exhaust requirements. All products are manufactured in the UK and distributed to over 90 countries worldwide. - Designed to enhance sound aesthetics for vehicles with particulate filters - Suitable for customers planning future turbo back upgrades - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 80.00 - Installation Time: 3 to 3.5 hours (including removal of OE system) - Race Product: No - EMarked: No Kit comes with: - F5150: Adaptors to OE - F5150 - MSAU744REP: LH Front Silencer Bypass - MSAU744REP - MSAU745REP: RH Front Silencer Bypass - MSAU745REP - MSAU746: Active Valved Centre Section - MSAU746 - MSAU747: LH Connecting Pipe - MSAU747 - MSAU748: RH Connecting Pipe (To Milltek OPF Back System) - MSAU748 - MSAU749: LH Rear Section - MSAU749 - MSAU750: RH Rear Section - MSAU750 - MSTIP271: LH Cerakote Black Oval Trim - MSTIP271 - MSTIP272: RH Cerakote Black Oval Trim - MSTIP272 - MSAU751: LH Valved Outlet (Inc Actuator) - MSAU751 Vehicle Compatibility: - 2020 and later Audi RS6 C8 4.0 V8 bi-turbo Performance Edition (Non OPF/GPF Models - USA/ROW Models) - 2019 and later Audi RS6 C8 4.0 V8 bi-turbo Performance Edition (OPF/GPF Models) - 2019 and later Audi RS7 C8 4.0 V8 bi-turbo (Non OPF/GPF US/ROW Models) - 2019 and later Audi RS7 C8 4.0 V8 bi-turbo (OPF/GPF Models)
