I just picked up my 2008 a4 three weeks ago and am looking for aftermarket upgrades that are the best to use; without voiding the warranty out. I've seen chips and some exhaust sites but I want to know without a doubt what are the best to use. Also looking for hid headlight assemblies, I don't like the stock ones and want a better look to the front end and better light dispersion. What do you guys suggest?

 

never mind this post, checked out the nuubie guide and had all my questions answered. But can any one tell me why the o8 a4's come with the s-line badge on the front grill?
