Performance Exhaust

The internal combustion engine is a big air pump designed to get air into and out of the motor in the most efficient manner. BBK headers & exhaust upgrades will in most cases slightly improve fuel economy depending on how restrictive the factory exhaust manifold or exhaust system is. As you will see with our line of “CNC-Series” performance headers, the goal is to design a header which has improved flow over stock but also balanced flow. In simple terms, the more even each header tube can be to each other then the better the overall efficiency and potential performance increase. With that in mind, it also boils down to how bad the original parts are designed from a flow standpoint as even on our “Shorty” style headers. Substantial power gains are still seen as the factory manifolds perform so badly. Depending on packaging parameters, our engineers always try to strike the best balance between performance and longevity and will use tube diameters and other means to also get the most out of each BBK performance exhaust upgrade.
