HKS Subaru Impreza WRX STI (GVF, EJ25) (10-14) Single Scroll Exhaust Manifold

HKS Europe, established in 1996, reaffirmed HKS’ commitment to global sales and customersupport. Based in the United Kingdom, HKS Europe is able to reach customers across all of Europe, Russia and South Africa with localised knowledge of the market demands which differ from region to region.

HKS’ presence in the UK allows HKS to stay at the pinnacle of automotive engineering both on and off the race track.

The best solution to reduce primary exhaust gas back pressure and supply smooth exhaust gas to the turbine. HKS supplies stock replacement type Stainless Exhaust Manifolds. Turbine performance is affected by the Exhaust Manifold.

The shape, diameter of pipes and production quality of Exhaust manifold between the engine and turbine affects the performance of the turbine. HKS Exhaust Manifolds are developed with know-how and data from the development of turbo technologies. The diameter of the pipes and design of the bends are designed for each engines performance and displacement. The welding portion between the flanges and pipes is flattened to reduce friction of exhaust gas.

As a result, response of the turbocharger at middle and high rpm range is improved. Both torque and horsepower will be increased.
