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 an increase in total system mass flow at the same boost pressure – translation: more power for you!
