HKS Stainless Steel Exhaust Manifold Subaru Impreza
Not tested on GC8 STI Ver.IV. Not for vehicle w. stock under cover.
STAINLESS EXHAUST MANIFOLD pulls out potential power from turbocharged engine.
The best solution to reduce primary exhaust gas pressure and supply smooth exhaust gas to turbine is replacement of exhaust manifold. HKS supplies stock replacement type Stainless Exhaust Manifold.
Turbine performance is affected by Exhaust Manifold.
Shape, diameter of pipes and production quality of Exhaust manifold between engine and turbine affects performance of turbine. HKS Exhaust Manifolds are developed with know-how and data from long time development experience of turbo technologies.
Diameter of pipes and design of bending are designed for each engine performance and displacement. Welding portion between flange and pipe is flattened to reduce friction of exhaust gas.
As a result, response of turbocharger at middle and high rpm range is improved. Both torque and horsepower will be increased.
There were many famous turbines in HKS' History. And that's the history of the tuning itself.
