Milltek Big Bore Downpipe with Catalytic Converter Bypass Pipes (for Original Cat-Back) for Audi RS6/RS7 C7 and S6/S7 C7 - Part Number SSXAU634

Description

Milltek Sport Big Bore Downpipes are ideal for improving performance and sound. They have a larger diameter than standard OEM parts, allowing significantly more space for exhaust gases to exit and pass through, improving efficiency.

We also removed the primary catalyst from the exhaust system to create a smoother exhaust, allowing the engine to run more efficiently and increase performance.
