About This Product
Experience unparalleled performance and durability with our enhanced Dodge/RAM truck exhaust manifolds, specifically designed for 5.7L HEMI engines. Our BD upgraded manifolds address common exhaust manifold bolt failures by incorporating extended fasteners and spacers that effectively withstand thermal expansion. In addition, we've engineered independent mounting locations for the heat shield, separating it from the mounting bolts to further enhance reliability. Crafted with precision, our BD Manifolds boast a robust, thicker design, and are constructed from high-silicon ductile iron to combat warping, ensuring your vehicle remains at peak performance for the long haul.

These manifolds will only fit the 2009-2022 classic DS body style NOT the 2019 + DT body style
This exhaust manifold kit fits 2009-2022* RAM HEMI 5.7L engines. *Note: 2019-2022 Classic body only.
What are the common issues this kit addresses?
This kit addresses common bolt and manifold failure, exhaust leaks, and warped manifolds in 5.7L HEMI engines.
What is included in the kit?
The kit includes all necessary gaskets and fasteners for installation.
What material is the manifold made from?
The manifold is constructed from high-silicon ductile iron, which adds strength and resistance to warping and heat dissipation.
How long does installation take?
The estimated installation time for this exhaust manifold kit is 4.5 hours.
Can I purchase just the driver's side or passenger's side manifold separately?
Yes, the kits are available as left only (Driver's side) PN 1041465, right only (Passenger side) PN 1041464, or both together PN 1041463.
How does this manifold prevent thermal expansion issues?
The manifold incorporates longer fasteners and spacers that resist breaking due to thermal cycling and has an engineered independent heat shield mounting location.
