Hello guys, I am new in this forum and this is the first time I post a thread. Let's get to the point, I have an '04 av6 that I want to change the stock exhaust with a Borla's. I am new in USA, so I don't know where should I sell the stock exhaust. Could you guys please help me? I also want to sell the stock suspension but don't know where to. Any help will be appreciated. Thanks!
