From 2017, many vehicles have been equipped with a 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 with particulate filters - Manufactured in the UK - Distributed to over 90 countries Specifications: - Pipe Diameter: 76.20 - Fitment Time: 1 to 1.5 hours (including removing OE system) - Race Product: No - EMarked: No Kit comes with: - Polished GT (round) 90 Exhaust Tip, Standard - MSAU529 - Rear Silencer Assembly (Valved) - MSBM246 - Outlet Pipe (Non-Valved) - MSBM277 - Outlet Pipe (Valved) - MSBM278 - LH Mounting Bracket - MSBM279 - RH Mounting Bracket - MSBM280 - Non Resonated Centre Section - MSBM306REP Vehicle Compatibility: - 2019-2020 BMW 1 Series M140i 3 & 5 Door (F20 & F21 LCI, OPF/GPF Only)
