Downpipe is typically the first element of the exhaust system located right after the turbocharger in turbocharged cars or directly after the exhaust manifold in naturally aspirated vehicles. It is usually made of stainless steel, heat-resistant stainless steel, or sometimes titanium. The diameter of the downpipe is often larger, sometimes several times larger than that of the stock exhaust system. When opting for maximum pipe diameter and full flow, other limitations of the stock exhaust system should also be modified to fully utilize the benefits of the downpipe.
This downpipe features: two lambda sensor ports, a pressure sensor hose connection, and reinforced mounting for structural support. It is made entirely of acid-resistant steel (T304, X5CrNi18-10, 1.4301, AISI 304, 0H18N9) and each component is manufactured using CNC technology. OE numbers include 1832989731318329897314. The condition is used, with thermal discoloration, but it is fully functional. This downpipe fits models originally equipped with a catalyst meeting EURO 6 standards.
