This is an Exhaust Manifold compatible with factory one made by stainless. We devised pipe shape and a diameter not to disturb a flow of exhaust emission and reviewed balance between exhaust flow quantity and exhaust pressure. As a result, start of a turbo in the whole rev became smooth. Especially, for the Subaru Impreza, it is possible to disappear to blow down completely by separating it into 1-2 and 3-4 just before the turbo becomes 50m/m by designing it to be 4-2-1 manifold, and designing it to stand up smoothly from the low rotation. JUN introduces completely different exhaust system compared with the maker of original exhaust manifolds.
