From late 2018, many vehicles have been manufactured with a Gasoline/Otto Particulate Filter to further reduce emissions. The Milltek Sport Particulate Filter-Back range is designed to compensate for the sound reducing qualities of the particulate filter and significantly improve the sound aesthetic of the exhaust system. 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. - Designed to enhance exhaust sound on vehicles equipped with particulate filters - Manufactured in the UK - Distributed to over 90 countries Specifications: - Pipe Diameter: 80.00 - Installation Time: 2.5 to 3.5 hours (including removing OE system) - Race Product: No - EMarked: Yes - EMark Number: AUDIS8 Kit comes with: - MSAU748: RH Connecting Pipe (To Milltek OPF Back System) - MSAU798: LH Lower Downpipe - MSAU799: RH Lower Downpipe - MSAU800: LH Front Silencer - MSAU801: RH Front Silencer - MSAU802: Active Centre Section - MSAU803: LH Connecting Pipe - MSAU804: LH Rear Silencer - MSAU805: RH Rear Silencer - MSAU806: LH Valved Outlet Pipe - MSAU807: RH Valved Outlet Pipe - MSTIP250: Polished GT (round) 115 Exhaust Tip Vehicle Compatibility: - 2020 and later Audi S8 D5 4.0 TFSI V8 Saloon / Sedan (OPF/GPF UK/Euro Models) - 2020 and later Audi S8 D5 4.0 TFSI V8 Saloon / Sedan - Standard Wheel Base (Non OPF/GPF US/ROW Models)
