After two years of design and testing, APS is proud to announce the release of the APS Tapered Turbine Entry Duct (Up-Pipe).
A complete bolt-on assembly including cast up-pipe and a truly innovative Double Wall 321 stainless steel flex coupling that incorporates an internal 321 stalinless steel Endurance flow tube.

To achieve high exhaust gas speed, the turbocharger entry duct must be manufactured with a precise internal taper. As it is all but impossible to achieve a precise taper in stainless steel tubing over the entire distance of the duct, the APS Tapered Turbocharger Entry Duct is cast in a high nickel content ductile iron. This material also provides maximum durability under extreme exhaust gas temperatures and it is the unique internally tapered profile that ensures optimum exhaust gas speed. The result is crisp turbocharger response and the highest horsepower possible under all driving conditions and at any engine speed.
An added benefit is with the high thermal inertia of this cast component, it ensures that the greatest amount of thermal energy is trasnferred to the turbocharger for even greater horsepower and crisp throttle response.
Smooth exhaust gas entry into flex coupling

Unlike up-pipes without 321 Stainless flexible coupling, the APS up pipe will not suffer from cracking or manifold stud breakages due to the expansion under extreme load and high exhaust gas temperature.
The APS Double Wall 321 Stainless Steel Flex Coupling is specifically designed and manufactured to suit the WRX and STI under high horsepower applications.
With an innovative internal 321 stalinless steel Endurance Flow Tube, the external Double Wall 321 Stainless Steel flex is insulated from high exhaust gas temperature to ensure total durability - whilst providing a stress free coupling between the exhaust manifold and turbocharger.
With a smooth internal profile, the Endurance Flow Tube also enhances exhaust gas flow for even greater horsepower and throttle response.

As a truly bolt on system, the APS Tapered Turbine Entry Duct matches the standard WRX and STI turbocharger entry port and stud pattern and is therfore suitable for use with the stock TD04 Mitsubishi turbocharger, the VF series turbochargers as well as the extensive range of APS S/R Series Ball Bearing Performance turbochargers.
The APS Tapered Turbine Entry Duct (Up-Pipe) provides optimum performance, response and component durability under extreme load and high horsepower applications. It is a perfect partner with the APS range of S/R Series Ball Bearing performance turbochargers.
Two years in the making and certainly worth the wait.
