BD Diesel 1045996-T6 Wastegated T6 Exhaust Manifold 20-Degree 45mm Port Cummins

The BD Diesel 1045996-T6 is a high-performance wastegated exhaust manifold engineered for Dodge Cummins 5.9L engines with aftermarket T6 turbocharger upgrades. The cast and machined wastegate port completely divides the manifold into two sections to retain the divided pulse manifold flow, protecting your turbocharger investment while maximizing exhaust flow.

Advanced Design Features:

• Internal geometry is optimized through Computational Fluid Dynamics (CFD), which increases flow throughout the RPM band for T4 and T6 based turbochargers
• Center mounted turbo flange is angled at an optimum 20° rather than 40º, simplifying installation of large frame turbos like S400 and S500 series
• Built-in heat expansion joints prevent cracking and the heavy cast HiSi Ductile Iron retains heat energy
• Ports and runners match the inlet gasket within 0.03" for maximum flow efficiency
• High-temperature black coating for heat retention and durability
• 1/8-NPT ports are pre-drilled and tapped for EGT sensors or other accessories

Wastegate Specifications:

• Wastegated manifold is machined for use with Turbo Smart 45mm Hyper Gate (sold separately)
• Gate port area is 1.67 sq. in. - 33% of T4 / 12% of T6 inlet
• Wastegate block-off plate and clamp provided for non-wastegate applications
• Better cylinder exhaust evacuation to keep EGTs down
• Combustion pulse remains constant with wastegate valve closed

What's Included: T6 exhaust manifold, mounting bolts, nuts, washers, hardware, wastegate block-off plate, and clamp. Replacement gaskets and manifold bolts not included and are available separately.

Important Notes: This exhaust manifold is not for use on stock turbo applications. It will require the use of a T6 turbocharger. Not legal for sale or use on vehicles registered in California.
