The aFe 46-40011 is an engine-specific Cast 304 stainless steel, with reinforcing rib and thick port flange; not a mandrel-bent exhaust tube or tip. This replaces the manifold feeding the turbocharger, not a complete exhaust system, muffler or tailpipe.

| 2003–2007 | Dodge Ram 2500 / 3500 | 5.9L Cummins inline-six turbo diesel |
46-40011: The December 2025 manual swaps the MAKE/MODEL/YEAR labels and prints L5; the exact manufacturer page and official order establish the 5.9L inline-six Dodge application. The gasket-set label's broader 98.5–07 wording does not extend this manifold to earlier engines. The guide's general band-clamp/V-band paragraph is not the manifold bolt torque or an added clamp kit. Generic Filter Included/Coupler Included fields do not establish an air filter or hose package.
| Detail | Value |
|---|---|
| Manufacturer Part Number | 46-40011 |
| Configuration | Engine-specific exhaust manifold; EGT probes and gauges are separate |
| Material / runners | Cast 304 stainless steel, with reinforcing rib and thick port flange; not a mandrel-bent exhaust tube or tip. |
| Finish | Cast stainless construction; no polished exhaust-tip package |
| Fasteners / torque | 32 ft-lb for the anti-seize-treated manifold fasteners in the illustrated factory sequence. Recheck connections after 100–200 miles. This is not a universal turbo-nut, port-plug or clamp setting. |
| Retained equipment / installation | Requires turbo removal and reconnection of its downpipe, outlet, oil lines and applicable electrical connector. Cut the original water-line bracket 2 inches from the water line as instructed, then install the supplied support. Restore the factory heat shield. |
| Emissions | Current exact page and December 2025 guide cite D-550-9; official indexed order names this exact part for 2003–2007 Dodge Ram 2500/3500 5.9L Cummins diesel pickups. Match the order's installation and stock-calibration conditions. |
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
An exhaust manifold for the listed 5.9L Cummins inline-six turbo diesel. It is not an entire exhaust or a guarantee of a particular sound level.
Which material and construction does this part use?Cast 304 stainless steel, with reinforcing rib and thick port flange; not a mandrel-bent exhaust tube or tip.
Are the required gaskets included?Six port gaskets are supplied as the exact gasket set. Do not treat the set's wider engine-year label as extra manifold fitment.
Does it include EGT probes or gauges?No such equipment is included in the exact contents. Match any separate probe to the actual port and seal unused openings.
What water-line or retained-equipment work is required?Requires turbo removal and reconnection of its downpipe, outlet, oil lines and applicable electrical connector. Cut the original water-line bracket 2 inches from the water line as instructed, then install the supplied support. Restore the factory heat shield.
What is the manifold torque and recheck interval?32 ft-lb for the anti-seize-treated manifold fasteners in the illustrated factory sequence. Recheck connections after 100–200 miles. This is not a universal turbo-nut, port-plug or clamp setting.
Are any exact-source packaging or procedure conflicts unresolved?The December 2025 manual swaps the MAKE/MODEL/YEAR labels and prints L5; the exact manufacturer page and official order establish the 5.9L inline-six Dodge application. The gasket-set label's broader 98.5–07 wording does not extend this manifold to earlier engines. The guide's general band-clamp/V-band paragraph is not the manifold bolt torque or an added clamp kit. Generic Filter Included/Coupler Included fields do not establish an air filter or hose package.
What emissions application is documented?Current exact page and December 2025 guide cite D-550-9; official indexed order names this exact part for 2003–2007 Dodge Ram 2500/3500 5.9L Cummins diesel pickups. Match the order's installation and stock-calibration conditions.

Match the exact engine and fuel-system generation before comparing a service replacement with a larger build component. HEMI ignition and valvetrain references require their own engine coverage and supporting build requirements; pickup parts naming another model also need explicit 2500 application.BD Diesel Transmission ChoicesCompare the BD Diesel valvebody reference with the separately listed 68RFE transmission-and-converter build package.
