This BD Diesel ported T4 exhaust manifold fits ‘98.5-‘14 5.9L and 6.7L Cummins powered Dodge Rams and allows you to run a T4 flanged turbocharger (T3 flange is stock). For maximum flow, this manifold features larger runner sizes and is cast with ports and runners that match the inlet gasket within 0.03-inch. Its built-in heat expansion joints prevent cracking, the heavy cast HiSi ductile iron retains heat energy, and is the entire manifold is coated with high temperature black. The center mounted turbo flange is angled at an optimum 20° (rather than 40º) and helps with mounting S400, Garrett, and other large turbochargers utilizing a T4 flange.
