Cummins N14 Late High Performance Exhaust Manifold Kit, 181050HP

Cummins N14 High Performance Exhaust Manifold Kit - Fits Years 1995 and Newer

This High Performance manifold includes additional manufacturing procedures and a special coating which further improves the efficiency of the manifold and the engine. The three individual sections are treated through an Isotropic Super Finishing (ISF) process which greatly polishes the inside and outside of each section. A polished interior reduces pressure loss in the manifold and allows for smoother gas flow into the turbo.
Next, the three sections are assembled with a high temperature sealant and are then coated with a "Thermashield" high temperature insulating ceramic coating, locking in the heat of combustion inside the manifold. This has two advantages: 1) less heat radiates out from the manifold which helps to keep the engine bay and engine cooler, and 2) the heat energy in the exhaust gas is not wasted and is instead channeled into the turbo, improving its performance and increasing the engine's efficiency.
After the coating is applied, the whole assembly goes through a final machining step in a specialized CNC which machines all the mounting surfaces in a single step, perfectly aligning them on the same plane. Such precision ensures a perfect mating contact with the head, reducing the peak stresses on the bolts, eliminating the problem of cracking around the bolt holes, and providing for a better, longer-lasting seal.
Before ordering, please ensure that your manifold has only two bolt holes at each exhaust port. These holes should be located diagonally from each other, as indicated in our photo. If your manifold has 3 or 4 holes at each port, you require the earlier, N14 Celect Manifold.

If you are unsure if this is the correct manifold for your application, please give us a call with your Engine Serial Number and we'd be happy to assist. 
Over time exhaust manifolds warp and develop cracks, leading to exhaust leaks and possibly exhaust fumes migrating into the operators cabin. This is why we manufacture our manifolds out of top quality cast iron. Our exhaust manifolds are designed to flow more efficiently, delivering better engine performance.
