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 exhaust system's sound aesthetic. All performance exhaust systems are designed for a wide range of vehicles. Milltek Sport focuses on continuous evolution, with research and development ongoing throughout the year 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 aesthetics - Compensates for sound reduction from particulate filters - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 76.20 - Fitment Time: 1 to 1.5 hours (including removing OE system) - Race Product: No - EMarked: Yes - EMark Number: M140OPF Kit comes with: - MSBM246: Rear Silencer Assembly (Valved) - MSBM277: Outlet Pipe (Non-Valved) - MSBM278: Outlet Pipe (Valved) - MSBM279: LH Mounting Bracket - MSBM280: RH Mounting Bracket - MSBM306: Resonated Centre Section - MSTIP217: Burnt Titanium GT (round) 90 Exhaust Tip, Standard Vehicle Compatibility: - 2019-2020 BMW 1 Series M140i 3 & 5 Door (F20 & F21 LCI, OPF/GPF Only)
