Thanks for the info. I have been tossing the idea of the magnaflow exhaust up, but i do not really want a loud, red-neck sounding exhaust on a luxury car. From what I have heard it isn't red-neck at all, but I want to be sure before I invest that kind of money. I want something with some throaty growl when I get on it but not a whole lot at idle. How did yours sound? Any suggestions from people who have the Magnaflow system? I have been to youtube but the videos are hard to tell from because of micing issues ect...
