i have had my 3 for almost a year now and have had no major problems with it yet. it is my daily driver and love driving it. the only thing is that if i have my car running and go around the back i hear the exhaust tip rattling. at first i thought it was rattling because of my subs but a quick mute of the stereo proved it is the tip. how the hell do i stop the rattling without buying a new exhaust (that will be later down the road). it is embarrassing having a ghetto ass rattle like that. any suggestions would be greatly appreciated thanks
