THE-Upgrade 08 exhaust housings are investment cast from heat-resistant 1.4848 stainless steel. They are designed for the S4/RS4 B5 2.7t. The machining is suitable for the OEM RS6 turbine wheel. We also offer machined exhaust housings for TTE780/TTE880. If other machining is desired, it must be done by the turbocharger manufacturer.
Advantages over the OEM RS6 exhaust hosuing:
Larger volute (08)
Flow optimized design
Lower exhaust back pressure
Optimized flow of the exhaust gas level
Larger inlet cross section
Downpipe flange with double bolt circle (RS4 / RS6) - when needed the orignal downpipe from the RS4/S4 can be installed at any time (e.g. exhaust emission test)
Optimized wastegate channel
Optimized and larger wastegaste flap
More throughput through flow-optimized bionic design
stainless steel 1.4848 (up to 1100 °C)Investment casting for uniform wall thickness and surface qualityThrough continuous CFD optimization, an almost constant response behavior despite the larger volute and a considerably higher peak performance could be achieved.
The company Reitsamer Performance achieved the previous maximum performance in connection with TTE880 of 942 HP and 1273 Nm.
We recommend using the original Audi bolts and nuts for assembly!Installation on the RS6 C5 is only possible in connection with a manual gearbox!
