You bought your Sierra 2500 HD Classic because its reliability and longevity appealed to your senses; so why would you settle for anything but the best when it comes to superior quality auto parts?

Why Exhaust Manifold replacement is so important.

Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on the quality and performance of the parts you use. Efficient combustion inside your GMC Sierra 2500 HD Classic engine depends greatly on your exhaust manifold, and its ability to funnel exhaust gas out of the cylinder head. Should you develop a leak in your GMC Sierra 2500 HD Classic exhaust manifold, then two negative side effects will result. First, some of the gases will not tumble as they should; lingering inside the exhaust manifold and interrupting your four-stroke cycle. 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.
