HKS Stainless Steel Equal Length Exhaust Manifold

The factory exhaust manifold in the Subaru STI leaves a lot of room for performance improvements. Although very reliable and robust in design, the factory header puts a limit on those of you with a larger horsepower goal. 

HKS, who are some of the founders in the aftermarket turbocharged performance industry, have developed a quality equal-length exhaust manifold that has been designed with smooth bends to provide an unobstructed flow path of exhaust gases straight to the turbocharger. This will improve the turbocharger response which will create more horsepower and more torque. 

This is an equal-length design that will produce an aggressive exhaust tone that will come provided with new gaskets and hardware making it ready to install right out of the box. This manifold has also been designed with a stock up-pipe flange to work with the factory or aftermarket up-pipes that utilize the OEM-like flange.
