Hummer H2 Replacement Exhaust Manifold Information


The exhaust manifold in your Hummer H2 traps all the exhaust fumes and channels it to the exhaust pipe. When your Hummer H2 is running, the pistons on each cylinder move up and down, taking in a fuel and oxygen mixture which is then ignited by the spark plugs. The waste gas is pushed up the cylinder by the piston. The exhaust manifold is over the cylinders, so once the exhaust fumes are pushed up and out of the cylinders, the fumes are contained by this critical component.

Original equipment manufacturer (OEM) exhaust manifolds are generally made from stainless steel. Aftermarket exhaust manifolds can be made of multiple materials that increase efficiency. Often the exhaust manifolds will be coated with ceramic finish or a heat-resistant material. These finishes make the transport of the exhaust fumes smoother. Many owners upgrade the exhaust manifold to increase engine power by decreasing the friction.


They are available for the following Hummer H2 years: 2008, 2007, 2006, 2005, 2004, 2003, 08, 07, 06, 05, 04, 03. This part is also sometimes called Hummer H2 Exhaust Manifolds. We stock exhaust manifold parts for most Hummer models including H3.

We stock these Exhaust Manifold brands for the Hummer H2: Dorman and Replacement.
