The Cummins N14 Celect Plus Exhaust Manifold has been designed to maximize the exhaust air flow, to reduce turbo lag time, and cool exhaust temperatures.

Stock and competitive products on the market fall short as their design constricts the airflow increasing the turbo response time. Hard angles of their design cause higher swirl rates and friction which will increase the exhaust temperatures putting more risk on the engine. With lower quality iron an exhaust manifold from a competitor or stock can weaken over time as the manifold expands and contracts it will develop cracks and even flake.

During the design process each port has been analyzed and tested to provide a balanced flow to the turbocharger. The diameter of the runners has been designed to produce, on average, a 20% airflow increase over a stock manifold. The gradual angles of the manifold have been built to reduce swirl rate resulting in cooler exhaust temperatures by 75-100 degrees. PDI manifolds are a big part in maintaining the best exhaust pressure to boost pressure ratios which will provide the potential for increased fuel economy.
