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 aesthetics - Compensates for sound reduction from particulate filters - Manufactured in the UK - Distributed to over 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 - MSTIP197: Cerakote Black GT (round) 76 Exhaust Tip - MSTIP197 - MSVW484REP: Front Silencer Delete Pipe - MSVW484REP Vehicle Compatibility: - 2019 and later Audi A1 40TFSI 5 Door 2.0 (207PS) with OPF/GPF
