The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles currently being driven today. When your GMC P25 left the factory, it was destined for a person with discerning taste who wants longevity in their automobile. Obviously, you didn't buy your P25 unless you wanted to buy horsepower and rugged design both rolled up into one automobile. GMC vehicle enthusiasts have become used to a certain level of dependability when driving their P25 around town.
Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on the quality and performance of the parts you use. In order to make the combustion process as efficient as possible inside your GMC P25 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 P25 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.
