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.

 

 

 

 

 

 

HKS Exhaust technology set targets to pull out 100% engine performance with the exhaust manifold. A lot of different approaches were tried for each vehicle to keep performance for  the middle rpm range and to improve horsepower at high rpm.
