Shop GMC K2500 Replacement Exhaust Manifold

The exhaust manifold for GMC K2500 captures the exhaust that is generated in the engine's cylinders. The collected exhaust is directed away from the engine and transferred into the atmosphere through the tailpipe. The exhaust manifold is made out of cast iron or high quality steel which is specially designed for high temperatures. Heat resilient materials are essential for exhaust manifolds because the temperatures of exhaust gases generated by internal combustion engines are extremely high. Eight cylinder vehicles made between 1998 and 2000 generally require two exhaust manifolds, mounted on both sides of the engine block. Four cylinder vehicles require one exhaust manifold mounted on either side of the engine block, depending upon the vehicle manufacturer. When installing or replacing the exhaust manifold, gaskets, mounting bolts, and heat shields are required. Replacing the exhaust manifold using an original equipment manufacturer insures proper fit and performance.
