Evo 4G63 HKS Exhaust Manifold



Evo 4G63 HKS Exhaust Manifold – 1419-RM001 – for models Evo 4/5/6/7/8/9

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 affect performance of turbine. HKS Exhaust Manifolds were 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 are also increased.

NOTE: No Air Return Holes. Changing the manifold can reduce exhaust pressure and sends exhaust gas smoothly to the turbo. HKS has lined up stock replacement manifolds for popular applications. Exhaust gas flow between the engine and turbo, i.e. the exhaust manifold can greatly affect turbo performance and is an effective way to extract the maximum from a turbo. Pipe shape and size are carefully considered using the wealth of knowledge and experience that HKS has built up over 35 years. Each engines performance is matched with the right pipe diameter and bends as well as careful attention to making sure that the joints which connect the pipes and flanges are as flat as possible to maintain smooth flow of exhaust gas through the manifold. The result is much improved turbo response at mid to high revs and an increase in torque and power.
