Product information:
THE- exhaust manifolds are cast from heat-resistant 1.4848 stainless steel. To meet the demand for high-quality exhaust manifolds, the design is made for ease of assembly. They also feature high durability and provide the best possible flow. During development, 3D scanning and 3D measurement were used to lay the foundation for design with CAD and CFD. With the help of bionic design, starting with our manifolds, a large number of optimization loops were performed until the final designs.
Advantages over the OEM part:
- More throughput through flow-optimized design
- All 3 cylinders have the same throughput with a tolerance of 1%
- For comparison: OEMs are manufactured with a tolerance range of up to 5%
- Although the left and right manifolds are not the same length, our design achieves almost the same throughput
Key information:
- Material: stainless steel 1.4848 (up to 1100 °C)
- Investment casting for uniform wall thickness and surface quality
- More space for fresh air pipes
- Turbocharger is in the OEM position
- Connection for OEM exhaust gas temperature sensors are provided on both manifolds
- Improved response and design for higher performance
Additional information:
- We recommend using the original Audi bolts and nuts for assembly
- For easier installation of the fresh air pipes, you will find a silicone water hose under "Options", which replaces the original water pipe to the expansion tank. Since this silicone hose runs differently than the original water pipe, there is more space in the area between the fresh air pipes and the manifold.
- Suitable fresh air pipes:
- We recommend the Stud bolts M8x46 incl. nuts on the cylinder head after each disassembly/assembly to prevent it from becoming loose/expanding.
