From late 2018, many vehicles have been equipped with a Gasoline/Otto Particulate Filter to further reduce emissions. The Milltek Sport Particulate Filter-Back range is engineered to compensate for the sound-reducing qualities of the particulate filter and significantly enhance the exhaust system's sound aesthetic. All Milltek Sport performance exhaust systems are designed 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 vehicles with particulate filters - Manufactured in the UK - Distributed to more than 90 countries Specifications: - Pipe Diameter: 70.00 - Fitment Time: 1 to 1.5 hours (including removing OE system) - Race Product: No - EMarked: Yes - EMark Number: A1GB Kit comes with: - F5107: Adapter to OE Downpipes 70 O.D. to 65.5 I.D. 140 long - MSAU762: Rear Silencer - MSAU762 - MSVW484REP: Front Silencer Delete Pipe - MSVW484REP - MSTIP196: Polished GT (round) 76 Exhaust Tip - MSTIP196 Vehicle Compatibility: - 2019 and later Audi A1 40TFSI 5 Door 2.0 (207PS) with OPF/GPF
