BD Diesel 1045947-T4 Exhaust Wastegated Manifold w/T4 Mount / 40-degree - Dodge 1998.5-2007 5.9L

Protect your turbocharger with a performance manifold designed with a waste gate in mind. Cast and machined wastegate port completely divides the manifold into two sections to retain the divided pulse manifold flow. Internal geometry is optimized through Computational Fluid Dynamics (CFD), which increases flow throughout the RPM band for your high flowing T4 of T6 based turbo. Thick-wall cast high silicone ductile iron retains heat energy. Precision slip joints allow the manifold to expand and contract, which reduces cyclic thermal fatigue and greatly increase manifold longevity. 1/8-NPT ports are pre-drilled and tapped.Better cylinder exhaust evacuation to keep EGTs down; Extracts exhaust pulses for quicker turbo spool; Machined for use with 45mm Hyper Gate or Turbo Smart; Block off plate and clamp provided; Gate port area is 1.67 sq. in. (33%); Improves turbo response; Thick walled high silicone casting for long lasting durability; High temperature POR 15 paint; Pre-drilled for pyrometer probes and pressure gauges; Gasket, Bolt and Spacers kits are available separately; Our goal is to be an innovative company and a world class manufacturer that distributes products Worldwide for North American Diesel vehicles.; Our goal is to be an innovative company and a world class manufacturer that distributes products Worldwide for North American Diesel vehicles.
