Milltek Sport Large-Bore Downpipes are designed to enhance both performance and sound. These downpipes feature a larger diameter compared to standard OEM parts, allowing more exhaust gas to exit the engine and pass through, which increases efficiency. When combined with a Hi-Flow Sports Cat, a significant increase in performance and a noticeable change in sound can be expected. All Milltek Sport performance exhaust systems are developed for a wide range of vehicles, with continuous research and development to meet performance exhaust requirements. All products are manufactured in the UK and distributed globally. - Larger diameter than OEM for improved gas flow - Designed for increased efficiency and enhanced sound - Manufactured in the UK and distributed worldwide Specifications: - Pipe Diameter: 76.20 - Installation Time: 3.5 to 4.5 hours (including removal of OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSAU783: Heat Wrapped LH Cat Downpipe - MSAU783 - MSAU784: Heat Wrapped RH Cat Downpipe - MSAU784 Vehicle Compatibility: - 2020 and later Audi RSQ8 4.0 V8 Bi-Turbo (OPF / GPF Equipped Models) - 2021-2024 Audi SQ7 4.0 V8 TT (Petrol OPF/GPF Equipped Vehicles Pre LCI) - 2020-2024 Audi SQ8 4.0 V8 Bi-Turbo (Petrol OPF / GPF Equipped Models Pre LCI)
