Obviously I meant from the factory, and not aftermarket options.

Your car will be louder and depending on whether its catted or cattless will determine the overall loudness. Cattless will be louder vs catted but both will increase sound but it shouldn't be crazy loud. Most consider JDL, Tomei, Grupple-S, and HKS to be quality headers. The factory only sells the stock header you already have.

@Cole is being sarcastic I believe, but it leaves a good point a lot of people are completely clueless on the forum even though there are multiple stickies of the correct course of action if you go that route
