How many Hp does adding a Cold Air and Exhaust add ? does anyone know. I have the headers too - but I dont want it too get too much louder. Will bolting the headers on increase the noise by a lot or a little - or not at all. Thanks for your help :cool:

Well, I know for a fact that my DC Sports header added a bit of highway loudness and a more deep and throaty growl at idle and low RPMS. If you don't like loud, just dynamat!

As for the hp increases. I am unsure, you might be able to find the info over at SL.
