Exhaust manifold kit for Jeep Grand Cherokee 5.7 from 2011 to 2021

Unfortunately, cracked and leaking exhaust manifolds are not uncommon on the Jeep Grand Cherokee. Achieve greater longevity with the improved exhaust manifold kit, which has been specially developed for 5.7L HEMI engines.
The BD Upgrade manifolds address common manifold bolt issues by utilizing extended fasteners and spacers that effectively resist thermal expansion.
Equally frequent cracks in the manifold are counteracted by a thicker wall thickness, which - in contrast to the OEM manifolds - is evenly thick at all points.
In addition, independent mounting points for the heat shield have been designed to separate it from the mounting bolts and further improve reliability.
Manufactured with high precision, BD manifolds feature a robust, thick-walled design and are made from high-silicon ductile iron to counteract deformation and ensure your vehicle stays in top shape for the long term.
