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 improve exhaust sound on vehicles equipped with particulate filters - Manufactured in the UK - Distributed to over 90 countries Specifications: - Pipe Diameter: 60.30 - Fitment Time: 2.5 to 3 hours (including removing OE system) - Race Product: No - EMarked: No Kit comes with: - MSPO308: PORSCHE CAYMAN 718 GT4 V2 LH VALVE ASSEMBLY - MSPO309: PORSCHE CAYMAN 718 GT4 V2 RH VALVE ASSEMBLY - MSPO262: Rear Silencer Assembly - MSPO263: Outlet Pipe - MSTIP250: Polished GT (round) 115 Exhaust Tip - MSTIP250 Vehicle Compatibility: - 2019-2020 Porsche Boxster 718 GTS 4.0 (OPF/GPF Equipped Cars Only - Pre Feb 2020 build only) - 2019-2020 Porsche Cayman 718 GT4 4.0 (OPF/GPF Equipped Cars Only - Pre Feb 2020 build only)
