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.
