| For minimum restriction and optimum
gas flow of exhaust gasses exiting the turbocharger, APS has engineered
the High Flow Turbo Outlet housing. This housing is designed for high exhaust
gas temperatures which are normal in high performance turbocharged engines.
Cast in high temperature ductile iron ensures maximum durability under high
rpm, load and boost conditions.
The shape of the exhaust immediately
after the turbocharger is critical not only for strong outright performance,
but for excellent turbo response and correct turbocharger and waste gate
operation. The exact optimum shape for the best performance possible
cannot be formed from steel tube and we at APS do not compromise on performance.
This third generation High Flow Turbine Outlet improves catalytic "light-off"
performance. It also reduces disturbance of the primary exhaust discharge
from the turbine wheel caused by the wastegate swing valve opening. The result
is a marked improvement in overall system efficiency..

This high flow housing bolts directly to the Mitsubishi TD04 turbocharger and the popular range of IHI VF series turbochargers. The outlet end bolts directly to a standard 3" exhaust flange (included with High Flow Turbo Outlet along with mounting hardware, gasket and stainless steel heat shield).
This is a highly recommended component for high performance WRX and STI engines.
