The perfect drop-in replacement. Fully divided pulse manifold made from high-silicon ductile iron is designed to withstand extreme temperatures and vibration. Great for both stock and performance trucks. Designed using modern technology that utilizes pulse flow for quick turbo spool. Precision slip joints allow the manifold to expand and contract, which reduces cyclic thermal fatigue and greatly increase manifold longevity.
