Diesel Power Source 3-Piece Exhaust Manifold, Dodge (1988-98) 5.9L Cummins 12V, w/gaskets
The DPS 3-Piece Manifold for the Dodge Cummins engine is both a great performance manifold and a factory replacement manifold. This 3-Piece Manifold is cast from Ductile Iron sililar to your turbine housing (which can handle extreme heat, without much expansion or shinkage). We've designed this manifold with flow bench testing to increase turbo spool-up, and increase exhaust gas efficiency, all while manitaining exhaust gas velocity, so the turbo will function optimally. We've made the end ports flow more similar to the center ports so the end ports EGT's won't be severly hotter than the center ports.
Some competitors exhaust manifolds boast "Huge runners, or Huge tube design", while this sounds appealing, too big of runners will actually slow the exhaust velocity, and then need to re-accelerate as it bottle necks through the turbo, causing a loss in horsepower, and spool-up. We have actually seen a competitors manifold decrease horsepower by 40 hp on a 400 hp truck.
Stock manifolds and one-piece competitor manifolds are known to shrink significantly, causing manifold-cracking, gasket problems, and exhaust flow problems created by exhaust port misalignment. Even stainless steel manifolds will shrink significantly, causing misalignment. The dirty little secret is that competitors stainless steel actually moves (expands and contracts) more than ductile iron does. Our 3-Piece Manifold, on the other hand, allows manifold to expand and contract with heat, eliminating warping and cracking to the manifold, eliminating the dreaded manifold shrinkage.
