yeah, if i were you id start talking to people who actually know stuff about cars. get most of your info from here. ask questions, search, etc. dont get you info from magazines and other people, unless they actually understand cars. dont get me wrong, i look at magazines all the time. i just dont use them as a source or information, i just look at the pics and occasionally get a good laugh out of some of the cars in them.
also, go with the full catback. or at the least custom piping with a good muffler.
