PAI Industries, Inc. Exhaust Manifold Kit Part No: 181026

The PAI 181026 Exhaust Manifold Kit is engineered specifically for Cummins 855-series engines, including the transition-era N14. Designed with a low mounting boss (current style), this kit includes all three manifold sections—front, center, and rear—as well as gaskets, studs, spacers, and hardware for seamless installation. Built to meet OEM specs and pulse-tuned for efficient exhaust scavenging, it helps reduce engine backpressure and thermal stress. With cross references to Cummins part numbers (3071485, 3801915) and Interstate-McBee equivalents, it delivers reliable, long-term performance. Backed by PAI’s manufacturing excellence and sold by Wofford Truck Parts, this kit is a trusted solution for heavy-duty rebuilds, engine swaps, and maintenance of on-highway Class 8 trucks.
