A combustion engine's main product is horsepower and torque, it's by-product is exhaust.
In order to be competitive in today's economic market this factory needs to produce torque efficiently. It has to use it's main ingredients of gas and air wisely and be able to rid itself of byproducts efficiently.
Exhaust is a by product of the explosions that are produced over a thousand time a minute in your engine. It is vented from the engine by way of the exhaust manifold through the catalytic converter, through the muffler and out of the exhaust.
Getting back to the engine for a minute, for it to be efficient it has to get rid of this exhaust quickly. Why? well inside your engine are things called pistons they suck in air and gas and spew out exhaust, while there trying to spew out the exhaust the exhaust ahead of it is trying to get out of the way, but it's having a bit of trouble. Instead of the pistons spending all their gas and air on producing torque there wasting a percentage of these resources because the back pressure of the exhaust gas is pushing back on the pistons. If you could reduce the back pressure you could increase the horsepower. This is where exhaust headers come into play.
Replacing the stock exhaust on your car with a sport or racing exhaust system will not only increase horsepower (6-18hp), but will also assist to give your car a more aggressive look and sound.
The average amount of Horsepower gain is around 8 to 14. It depends on the quality of the stock header your replacing.
Most high-end header companies tune the resonance of the header to create a pulse wave to suck the exhaust gases out, creating a more efficient exhaust scavenging which is really important in header design.
Headers are designed in different exhaust ratios from low end performance to high end performance. If you do a lot of city driving or if you want better take off when pulling a load you'd want a header tuned for low end performance. If you want better performance for the open road at high speed you'd want a header tuned for the high end.
