WHEN YOU BUY 1 5.9L Common Rail Cummins Exhaust Manifold Stock Mount Dodge 2003-2007 - 1045987 YOU QUALIFY FOR THESE SAVINGS!
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.

This two-piece manifold is great in that it allows it to move with the temperature changes that the cast iron stock manifold eventually succumbs to. The biggest issue is #5 cylinder and the top bolt. The design was was not good in that the clearance to get a socket on it was too tight. I had to lathe down both the bolt shoulder and my socket to get it past the pipe to torque it down. I have read where others had the same issue. Otherwise, I really like the manifold.
