hammer and i have discussed this before, the extreme is the loudest, but sounds more of a muscle car, and the vortex is a little less loud but sounds more like a truck. but it all depends on what you want. its your opinion and your the one who makes the payments. thats just my take on it.

oh btw hammer, the vortex WILL be louder than my 40 series correct? especially since im going DO instead of SO which i have right now?

 

Headlights are H13, fogs are 9006 or 9007.
