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 enhance the exhaust system's sound aesthetic. All performance exhaust systems are developed for a wide range of vehicles. The research and development team works 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 improve exhaust sound on particulate filter-equipped vehicles - Manufactured in the UK - Distributed to more than 90 countries Specifications: - Pipe Diameter: 70.00 - Installation Time: 2 to 2.5 hours (including removal of OE system) - Race Product: No - EMarked: Yes - EMark Number: M3M4OPF Kit comes with: - F20370: Brace Bar - MSBM256: Rear Silencer - MSBM256 - MSBM269: Rear Silencer Connecting Pipe Left Hand - MSBM269 - MSBM270: Rear Silencer Connecting Pipe Right Hand - MSBM270 - MSBM311: Centre Section (EC Approved) - MSBM311 - MSTIP193: Brushed Titanium GT (round) 90 Exhaust Tip, Standard - MSTIP193 Vehicle Compatibility: - 2019-2020 BMW 3 Series F80 M3, M3 Competition & M3 CS Saloon (OPF/GPF Models Only) - 2019-2020 BMW 4 Series F82/83 M4 Coupe/Convertible, M4 Competition & M4 CS Coupe (OPF/GPF equipped models only)
