The BD Diesel Pulse Exhaust Manifold is a heavy-duty drop-in replacement designed to eliminate the common cracking and leaking issues found in factory units. Cast from high-silicon ductile iron, this manifold is engineered to withstand extreme exhaust gas temperatures and vibration. Its fully divided pulse design optimizes internal geometry, improving exhaust flow and turbocharger spool-up compared to standard cast manifolds.

To solve the problem of cyclic thermal fatigue, this manifold features precision-machined slip joints. These joints allow the manifold to expand and contract freely during heat cycles, preventing the stress-induced cracking that often plagues one-piece designs. This manifold comes pre-drilled and tapped for pyrometer probes, making it ready for EGT sensor installation.

• Direct replacement for Cummins OE # 3946036
• High-silicon ductile iron construction for superior heat resistance
• Fully divided pulse design for improved turbocharger response
• Expansion slip joints prevent cracking and exhaust leaks
• Pre-drilled and tapped for pyrometer probes
• Compatible with both stock and performance turbo configurations
• Manufacturer Part Number: 1045947

Note: Gasket, bolt, and spacer kits are available separately.

Resolve the chronic issue of manifold warping and broken mounting bolts on the 3.5L EcoBoost engine with the BD Diesel Upgraded Exhaust Manifold Kit. These manifolds are engineered with a robust, thicker design using high-silicon ductile iron to withstand extreme thermal cycles without distorting. To further prevent fastener failure, BD Diesel added two additional mounting holes per manifold and utilizes 15mm longer extended studs and spacers to better accommodate thermal expansion.

Beyond durability, these manifolds provide a 16% increase in flow capability over the factory units, improving engine efficiency. This kit is 50-state emissions legal (CARB EO No. D-553-27) and includes all necessary gaskets and hardware for a complete installation.
