Careful attention to tube diameter, smooth radius mandrel bends and muffler design is essential for high performance. With 20 years of experience in exhaust system design, we have built a superb exhaust system.   

Exhaust system design parameters immediately after the turbocharger are critical not only for outright performance, but for optimum torque and turbo response. The optimum internal profiles cannot be achieved with twin pipe or bell mouth pipes. APS has engineered the High Flow Turbo Outlet housing for extreme gas flow and high exhaust gas temperatures which are normal in high performance turbocharged engines. Cast in high temperature ductile iron ensures optimum internal shape and maximum durability under high rpm, load and boost conditions. 

The end result is an exhaust system that produces high outright power with stronger mid range torque than fabricated turbine outlet style exhausts. All this with improved turbo response (less lag) when running large turbochargers and maximum durability.
