The car I purchased has Firefly exhaust that are 2.5". Personally I like the deeper sound of the stock SPF pipes that are local to me but I'm not going to make a change. These pipes get loud at WOT but they are nice when cruising and haven't bothered my ears at all. They have been on the car a few years and have zero discoloring......mine have a strange look they appear to be a dull aluminum they are not shiny.
