The function and purpose of Exhaust Manifold.

Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on how well you maintain your engine and exhaust parts. In order to make the combustion process as efficient as possible inside your GMC Sierra 2500 HD engine depends greatly on your exhaust manifold, and its ability to funnel exhaust gas out of the cylinder head. If a crack forms in your GMC Sierra 2500 HD exhaust manifold, then you can count on a couple of problems. First, your exhaust flow will change; potentially reversing the direction of the gases inside the exhaust manifold back into the combustion chamber. Second, exhaust gas will escape before they can be cleaned by your catalytic converter; making the inside of your car smelly and filling it with carbon monoxide and noxious fumes.

ATP exhaust manifolds transport burnt exhaust gasses from the engine to the exhaust system. Over time exhaust manifolds can crack or warp releasing hot exhaust gas into the engine compartment. These gases can find their way into the passenger cabin creating a dangerous situation. The best way to repair the broken manifold is to replace it with a new one. ATP Exhaust manifolds are designed to fit and function like the original part restoring the exhaust system by eliminating the dangerous leaks.
