This Smeding Diesel 2 - piece OEM replacement exhaust manifold is a perfect fit for 2007.5 - 2018 Dodge/RAM 6.7L Cummins engines. It replaces the factory manifold with a two - piece semi - divided design. This setup offers faster turbo response and better reliability. The two - piece design allows the metal to expand and contract, reducing thermal fatigue and significantly increasing the manifold's lifespan. Key features include being cast from high - silicon ductile iron to handle extreme temperatures, thick - walled castings to prevent cracking and exhaust leaks, full EGR compatibility, and a perfect fit for the OEM turbo flange on 2007.5 - 2018 6.7L Cummins engines.

Using this exhaust manifold is straightforward. First, make sure your engine is the 2007.5 - 2018 Dodge/RAM 6.7L Cummins. Then, carefully remove the old factory manifold and install this replacement. When installing, ensure all connections are tight to prevent exhaust leaks. As for maintenance, check the manifold regularly for any signs of cracking or exhaust leaks, especially after long - distance drives or heavy - duty use. If you notice any issues, it's best to get it inspected or repaired right away. Also, since it's made of high - silicon ductile iron, it can handle extreme temperatures well, but try to avoid overheating the engine as much as possible to keep the manifold in good condition.
