T6 Mount Stainless 2nd Gen Swap Exhaust Manifold for Dodge Ram 2500 3500 (1998-2019) 5.9L 6.7L Diesel

High-Flow T6 Mount 2nd Gen Swap Exhaust Manifold for 1998-2019 Dodge Ram 2500, Ram 3500 (BR/BE, DR/DH, DJ/D2)

What it Does: The T6 Mount Stainless 2nd Gen Swap Exhaust Manifold relocates the turbocharger to a centered 2nd-generation position on the 1998-2019 Dodge Ram 2500, Ram 3500 to optimize pulse scavenging and support large-frame T6 performance turbochargers.

The Stock Dodge Ram 2500, Ram 3500 Thermal Fatigue and Flow Imbalance

Factory exhaust manifolds on ISB 5.9L and ISB 6.7L Cummins engines utilize rear-biased turbo placement and brittle cast iron construction. Under elevated drive pressures and thermal cycling, the OEM iron shrinks and expands unevenly, leading to warped flanges, blown exhaust gaskets, and stress cracks across cylinder ports 3, 4, and 5. Furthermore, the asymmetrical runner architecture creates disparate exhaust gas backpressure between front and rear cylinders, spiking rear-cylinder Exhaust Gas Temperatures (EGTs) and choking high-RPM turbine efficiency on BR/BE, DR/DH, and DJ/D2 platforms.

The Engineering Solution

Engineered for high-stress towing, competition sled pulling, and drag setups, this manifold adopts a 2nd-gen center-drop configuration to balance exhaust pulses equally across all six cylinders. Cast from high-grade stainless steel, this unit withstands extreme thermal expansion without warping or embrittlement. The manifold features thick-wall directional runners and a precision CNC-ported center collector that dramatically reduces boundary-layer turbulence before entering the divided T6 turbine footprint. Pre-tapped dual 1/8-inch NPT drive-pressure and pyrometer ports allow accurate, real-time monitoring of critical exhaust telemetry.

Frequently Asked Questions

Does this fit the BR/BE, DR/DH, and DJ/D2 Ram 2500, Ram 3500?

Yes, this manifold bolts directly to the cylinder head of 1998-2019 Dodge Ram 2500 and 3500 trucks equipped with the ISB 5.9L or ISB 6.7L engine in a 2nd-gen swap configuration.

Can I bolt my factory stock turbocharger directly to this manifold?

No, this manifold features an oversized T6 turbine flange and requires an aftermarket T6-flanged turbocharger along with custom 2nd-gen swap hot-pipe plumbing.
