Milltek Large Bore Downpipes & Hi-Flow Sport Pipes for C7 Audi RS6 / RS7 / S6 / S7

Milltek Large Bore Downpipes & Hi-Flow Sport Pipes for C7 Audi RS6 / RS7 / S6 / S7

Milltek’s selection of cast downpipes is engineered to improve gas flow and heat management, aiming to elevate efficiency and performance. Featuring the HJS High-Flow Sport Pipe, known as the premier aftermarket catalyst, it is designed to exceed the density of OEM catalysts while maintaining compliance with emissions standards for everyday driving. In contrast to the typical 500-600 cells found in standard OEM catalysts, Milltek’s high-flow catalyst minimizes this to 200 cells. This reduction creates a more open system that greatly enhances gas flow and performance.
