BD DIESEL 1046065 EXHAUST MANIFOLD KIT – DODGE RAM 2007.5–2018 6.7L CUMMINS 2500/3500 (INCLUDES GASKETS & BOLTS)

Product Description

The BD DIESEL 1046065 Exhaust Manifold Kit is a heavy-duty, fully divided pulse manifold upgrade designed for 2007.5–2018 Dodge Ram 2500/3500 trucks equipped with the 6.7L Cummins engine. If you’re dealing with warped factory manifolds, cracked runners, broken bolts, or persistent exhaust leaks, this BD Diesel manifold kit restores proper exhaust flow while significantly improving long-term durability under heat cycling and vibration.

Built from high-silicon ductile iron, the BD Diesel pulse manifold is engineered to withstand extreme temperature swings (including high heat events like regeneration cycles) while maintaining sealing integrity. A thick-wall casting and precision slip-joint design allow controlled expansion and contraction to reduce cyclic thermal fatigue — helping prevent cracking and exhaust leaks that are common with OE manifolds. This complete kit includes the hardware you need for a proper install, including new gaskets, spacers, and Grade 10.9 black oxide-coated bolts.
