This replacement manifold carries a larger T4 flange, angled at 20 degrees, so you can swap the stock turbo for a bigger one that still sits in the factory location.
It is a fully divided pulse design in high-silicon ductile iron, using exhaust pulses for quicker spool and more power. Precision slip joints let it expand and contract, cutting thermal fatigue for a longer life.
