Description:
The THE-Upgrade 08 exhaust housing is cast from heat-resistant stainless steel 1.4848 using the investment casting process. They were developed for the S4/RS4 B5 2,7t engine. 
 
The housing is suitable for the OEM RS6 turbine wheel.
We also offer machined exhaust housings to suit,  TTE550 / TTE600/TTE780 / TTE880 /
 
Advantages over the OEM RS6 Exhaust housings :
Larger volute (08) 
Flow-optimized design
Lower exhaust back pressure
Optimized flow of the exhaust gas level
Lower EGT compared to RS6 OEM housings
Higher power compared to RS4 or RS6 OEM exhaust housings 
Larger inlet cross-section matched for THE Tuner exhaust manifolds
Downpipe flange with double bolt circle (RS4 / RS6)
Optimized wastegate channel for no boost creep
Optimized and larger wastegaste flap
 
Key data:
More throughput through flow-optimized bionic design
Material stainless steel 1.4848 (up to 1100 ° C)
Investment casting for uniform wall thickness and surface quality
Through 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 942 HP 1273 Nm was achived not using Ethanol. 
One set includes two turbine housings with installed wastegaste flaps
Supplied to suit RS6 exhaust turbines
 
Extra information:
We recommend using the original Audi bolts and nuts for assembly!
Installation on the RS6 C5 is only possible in connection with using manual gearbox!
