4.0 TFSI EA824 upgrade Turbo exhaust manifold BAR-TEK®

Upgrade Exhaust manifold suitable for the Audi 4.0L TFSI engines as in the RS6 and RS7 C7. The exhaust manifold are the result of extensive development work on the RS6. Thanks to the CAD and CFM-supported design and very complex 1.4849 stainless steel casting, even temperatures of 1100°C are no problem for the exhaust manifold. The biggest problem with the standard exhaust manifold is that its diameter is far too small. Upgraded superchargers only make limited sense in conjunction with the standard manifolds. The exhaust valves are forced open due to the high exhaust back pressure, resulting in misfiring. With our manifolds, we have maximised the cross-section and all cylinders are brought together. The back pressure is significantly reduced. This results in more power and lower exhaust gas temperatures. Thanks to the flow-optimised design, projects with well over 1,000 hp can also be implemented. By retaining the original flanges, the turbos fit perfectly to the exhaust manifold without any modifications. Features: Pipe guide size 1.4849 cast stainless steel for temperatures of 1100°C better response behaviour more power 1.4849 cast stainless steel. The best of the best! We only use the materials with the best properties for racing applications. We have therefore decided in favour of a heat-resistant stainless steel casting with the little-known name "1.4849" as the alloy for our exhaust manifold. It consists of a complex mixture of chromium, manganese, molybdenum, nickel, niobium, phosphorus, sulphur and silicon. The key strengths of the material 1.4849 include in particular its heat resistance up to 1100 degrees Celsius and its high elongation at break. This makes it the material of dreams when it comes to the highest thermal and mechanical loads - and like it is made for demanding use in motorsport. It was therefore clear to that we only wanted the best of the best for our components and your tuning projects! Attention: The exhaust manifold for the 4.0L TFSI EA824 are supplied without thermal insulation, as this can only be fitted after the turbine housing has been welded on! Without insulation, there is a risk of fire damage to the vehicle, so it is essential to use these exhaust manifold with insulation!!! The installation of power-boosting components requires careful handling and specialised knowledge. The engine and the entire drivetrain must be in a performance-appropriate condition.
