I am looking to buy the following:

(1)OEM factory stereo with CD player and aux input or equivalent, easy, plug and play stereo (for cheap$) that fits into factory dash

(2)HID headlights or anything easy to install that will brighten my night time driving - brighter the better. Here I am willing to go a bit more $

(3)Exhaust - louder the better but no drone. Maybe a corsa or borla? I do not want to sacrifice low RPM torque either
