High-flow downpipe from Milltek Sport dedicated to BMW M340i/M440i G20/G22
The downpipe is equipped with a sports catalyst with a density of 200 CPSI. Modifying the front part of the exhaust significantly reduces back pressure, which translates into improved car performance. The component is made of stainless steel using casting methods. This reduces the number of welds, allowing for better thermal properties.
The downpipe has been designed to connect with Milltek Sport's Cat-back exhaust or the stock exhaust system. The component is perfectly fitted to the car, and installation does not require additional modifications.
