Product Details & Specifications

Fits Cummins 855 Small Cam and Big Cam I, II, III, IV NT and NT88 engines, including Celect Applications.

Our New Style manifold features Low Mounting Bosses at each of the 6 ports. It was designed to replace the original High Mount design manifold in all applications. You will now use a bolts with spacers instead of a clamp at each port. The old, high mount style had integrated spacers that were cast as part of the manifold. These were prone to failure and cracking. The new style manifold utilizes a separate spacer, that cannot crack, because it is not part of the manifold. If you are upgrading from the old style, you will find that our kit includes all spacers needed to upgrade to this newer design.

Please note: The original 3801322 Exhaust Manifold used sealing rings between the end and center sections. Through the years, these sealing rings have commonly failed due to repeated exposure to extreme heat cycles. When these sealing rings fail, exhaust leaks become present.

The new 3801915 exhaust system was designed to replace the original style manifold in order to offer a longer lasting, more superior product. It features a precision machined, slip-fit connection between end and center sections. No sealing rings are used with the new system. They are eliminated entirely. You will no longer have to worry about a failed seal causing unwanted noise, decreased engine performance or replacement down-time.

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.
