The Series 60 Non-EGR Exhaust Manifold has been designed to maximize the exhaust air flow to reduce turbo lag time and reduce exhaust temperatures.

Stock and other manufacturers fall short as their design constricts the airflow increasing the turbo response time. Hard angles and rough surfaces can increase swirl rates and friction, increasing the exhaust temperatures putting more risk on the engine. Lower quality exhaust manifolds 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 of the Series 60 Non-EGR Exhaust manifold 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.

PDI uses only the best material for our products. We use a superior grade of High Silicon with Molybdenum Ductile Iron (HSMD) that eliminates weak points such as warping, cracking, and center divider failure from heat erosion. This material, combined with a redesign of the mounting surfaces, eliminates common failures due to a fatigued manifold.

The Series 60 Non-EGR Exhaust Manifold has been so well designed it has a 2yr unlimited mile warranty. Available for 1994-2003 Detroit Series 60 Engines.
