*Improved  quality and with  V-band connection*

The stainless steel ø 76mm downpipe significantly reduces back pressure, relieving the turbo which in turn brings more power, torque and lower exhaust gas temperatures. The post-cat sensor may need to be programmed out. The downpipe is made of stainless steel except for the flanges, which are made of steel so that they do not warp and thus prevent leaks. The flange surfaces are machined flat. There are 2 lambda sensor connections M18x1,5mm welded in. The 200 cell cat has a diameter of ø 100mm. The downpipe sits between the turbocharger and the exhaust system. The connection to the exhaust is like the original. A power output of up to max. 400HP can be driven, of course the other components such as the exhaust system, injectors, manifold, intercooler, turbocharger must also be installed and the software adapted accordingly. Upgrade turbochargers such as K04-001 plug & play also fit the downpipe.

Registration according to §21 StVZO must be carried out by an officially recognized expert. Registration cannot be guaranteed. Since the exhaust behavior depends on several properties such as exhaust gas temperature, engine power, displacement etc., the specified Euro standard cannot be guaranteed.
