The process of customizing a Corvette for performance can be approached in several ways, but one of the best is to upgrade the exhaust system. Like anything else, a car needs to breath. A C7 sucks air in through its intake manifold to use in combustion. Removing the waste products after the cylinder fires is the job of the exhaust system, and if it does not do it efficiently, the gasses that are left behind will impede the next round of combustion and keep the Vette's small block V8 from turning out all the power possible.
The amount of gas that the exhaust can remove is dependent on two things. One is the internal diameter of the pipes in the exhaust system. These pipes are like a storm drain during heavy rain--if the amount to be removed exceeds the capacity of the drain, then water will back up. Replacing existing pipes with larger ones yields an immediate increase in performance.
The second method of improving exhaust is less intuitive. Gas flows in certain ways, and if it hits a solid object like the side of a pipe, it creates turbulence and slows the flow, sometimes enough to create back pressure. The twists and turns of a set of headers are prime turbulence territory, unless they are specifically engineered to prevent it. Putting in racing heads, particularly heads "tuned" for maximal performance at a particular rpm, can result in spectacular improvements.
