Well, headers alone will not add significant performance gains. As 68 TT mentioned about 5-10 HP on a stock engine. From my experience you have to look at a complete engine in combination with drivetrain. Engine is nothing more than air pump which has finite volumetric efficiency. This discussion can go on forever, but a total package should be considered vs. individual pieces. Some parts work better than others when combined in engine package.
