Sentra Headers
Your factory auto exhaust manifold is designed only in part for efficiency and power. As a result, maximum exhaust flow (power) is not achieved using factory headers, regardless of other performance exhaust modifications. To maximize flow and power, a better design is required. Maximize Flow to Maximize Power with replacement.
PRIMARY PIPE DIAMETER
The primary pipes are the main components of any style of tuned header. The most important consideration when selecting headers is the diameter of the primaries. According to the many header company tech folks we talked to, one of the most common mistakes Tuners make when buying headers is getting pipes that are too large in diameter.
The diameter of the primary pipes directly affects the speed (or flow velocity) of the exhaust mixture traveling through them. Simply put, gas moves faster through a small tube than a large one. Change the pipe diameter and you change that speed. You also change the rpm where the torque peak occurs. The lower resistance of a large-diameter header moves the torque peak into higher rpm; a smaller-diameter pipe moves the torque peak to a lower rpm. Bolt on a set of headers that are just too big and your torque peak will move so far up the rpm range, you'll never see it again-and you'll wonder why your new manifold screwed up your motor.
For a normal small-block street engine operating in the 1,500- to 3,500-rpm range, most of the manufacturers we talked to recommended 1 1/2- to 1 5/8-inch-diameter primaries, as a rule of thumb, for providing plenty of low- to mid-range torque.
