Exhaust Manifolds | 2019-2024 Ram 6.7 Cummins

Beginning with model year 2007.5 and the release of the emissions equipped 6.7L Cummins power plant, there were some major changes made related to the previous exhaust manifold design. One of the biggest changes relates to the fact that these trucks were now EGR equipped, meaning an EGR (Exhaust Gas Recirculation) Cooler was mounted to the top of the manifold, connected via two ports to allow exhaust to enter the cooler chamber. Secondly, this was also the release of the VGT (Variable Geometry Turbo) that did away with the standard T3 mount that had been used for years. The VGT now used its own proprietary sized turbo mounting flange. All of these changes made for a very unique manifold. However, one thing that remains unchanged over the years is the fact that the factory exhaust manifold is restrictive and prone to cracking.
