The hiss is almost the same with the headers as the test pipes. The one trade off is the headers promote less drone inside the cabin because they promote a higher exhaust note. The exhaust will not be as deep and bassy. Some may like it and some may not!

As far as what causes the hiss, I do not have a definitive answer so i do not want to speculate. Obviously the sound is promoted by aftermarket exhaust components because the tubing wall is thinner and the sound escapes easier.
