Milltek Sport Large-Bore Downpipes are designed to improve 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 from a catalyst. All Milltek Sport products are manufactured in the UK and distributed to over 90 countries worldwide. - Larger diameter than OEM for increased gas flow - Designed for improved performance and sound - Compatible with Catalyst Bypass Pipe for significant power gains Specifications: - Pipe Diameter: 76.20 mm - Fitting Time: 3.5 to 4.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - MSAU783REP: Heat Wrapped LH Decat Downpipe - MSAU783REP - MSAU784REP: Heat Wrapped RH Decat Downpipe - MSAU784REP - MSAU792: Downpipe Fitting Kit for Non OPF Cars Vehicle Compatibility: - 2020 and later Audi RSQ8 4.0 V8 Bi-Turbo (Non OPF / GPF Equipped Models) - 2021-2024 Audi SQ7 4.0 V8 TT (Gasoline Non-OPF Equipped Vehicles Pre LCI) - 2020-2024 Audi SQ8 4.0 V8 Bi-Turbo (Non OPF / GPF Equipped Models Pre LCI)
