This video shows you how to install an exhaust manifold on your 2003-2021 Chevrolet Express. The exhaust manifold collects the combustion gasses from your vehicle's engine, and directs them to the rest of the exhaust system. Frequent heating and cooling can lead to cracks or leaks. Installing a new exhaust manifold is often the only solution.
