The function and purpose of Exhaust Manifold.

Reducing harmful hydrocarbons and noxious gases that come from your car or truck depends on your use of properly functioning exhaust and emissions parts. Efficient combustion 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 two negative side effects will result. First, your exhaust flow will change; potentially reversing the direction of the gases inside the exhaust manifold back into the combustion chamber. Second, you will emit exhaust gases before they reach the catalytic converter; creating an unpleasant smell and potentially hazardous condition for you and your passengers.

There's no better place for what you need.
