The FP manifold for the EVO4-9 features 20% larger runners and collector entry angles that would make a tubular header blush. It is constructed from a durable, high temperature alloy that resists cracking and is compatible with the factory heat shield. In house testing results show lower exhaust pressure in the collector area and increase in total system mass flow at the same boost pressure - translation: more power for you!
Selecting gaskets includes a manifold to head gasket and a divided turbine housing inlet gasket.
Note: Product in picture has optional coating.
