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 used with the Catalyst Bypass Pipe, significant power gains can be achieved without restriction on gas flow caused by a catalyst. All Milltek Sport performance exhaust systems are manufactured in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM for improved gas flow - Designed for increased efficiency and performance - Compatible with Catalyst Bypass Pipe for significant power gains - Manufactured in the UK and distributed globally Specifications: - Pipe Diameter: 80.00 - Installation Time: 4.5 to 5 hours (including removal of OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSAU757REP: Heat Wrapped De-Cat Downpipe with OPF Bypass (LH) - MSAU757REP - MSAU758REP: Heat Wrapped De-Cat Downpipe with OPF Bypass (RH) - MSAU758REP - MSAU759: LH Connecting Pipe (To Milltek OPF Back System) - MSAU759 - MSAU760: RH Connecting Pipe (To Milltek OPF Back System) - MSAU760 - MSAU792: Downpipe Fitting Kit for Non OPF Cars Vehicle Compatibility: - 2020 and later Audi RS6 C8 4.0 V8 bi-turbo Performance Edition (Non OPF/GPF Models - USA/ROW Models) - 2019 and later Audi RS7 C8 4.0 V8 bi-turbo (Non OPF/GPF US/ROW Models) - 2020 and later Audi S8 D5 4.0 TFSI V8 Saloon / Sedan - Long Wheel Base (Non OPF/GPF US/ROW Models) - 2020 and later Audi S8 D5 4.0 TFSI V8 Saloon / Sedan - Standard Wheel Base (Non OPF/GPF US/ROW Models)
