Product description:
The ø 76mm stainless steel downpipe significantly reduces backpressure, which relieves the turbocharger, resulting in more power, torque, and lower exhaust temperatures. The post-catalyst sensor may need to be programmed out. The downpipe is made of stainless steel except for the flanges, which are made of steel to prevent warping and thus avoid leaks. The flange surfaces are machined, and the V-band connection is male / female, which self-seals and self-centers. There are 2 lambda sensor connections M18x1.5mm and an Interlock flexpipe welded in. The connection to the turbo is with a three-bolt flange to which a V-band connection is attached. This is then connected to the first pipe section of the downpipe, allowing the upper part of the downpipe to rotate. The downpipe sits between the turbocharger and the exhaust system. The connection to the exhaust is as original. It can handle up to 450 hp, but of course, other components such as the exhaust system, injectors, manifold, intercooler, and turbocharger must be installed and the software adjusted accordingly. Upgrade turbochargers such as K04-023 also fit the downpipe plug & play. The downpipe is replaced 1:1 with the original.
