The reason that the full length headers are the best is that they are typically designed to improve the scavenging effect of you exhaust system. The length of the primaries corresponding to which cylinder and firing order, if designed properly, will actually help suck air from the cylinders. This helps free horsepower and torque by putting less of a load on the engine. The less work the engine has to do just to run, the more efficient it will be, resulting in better performance. Smaller exhaust pipes to a limit will give you better torque because of the back pressure. However, smaller pipes can possibly not be big enough to flow efficiently at the higher rpms, causing horsepower to drop off on the top end. If possibly, get Long Tube headers; Hedman, Hooker or another reliable exhaust manufacturers; and 2.5" dual pipes with some free flowing mufflers. The design of the headers can also influence sound but this is not a big factor because you can't tell unless you try different brands.
