I mean, really? You just bought a 2014 new car and you want to slap on somebody's sloppy seconds in used exhaust parts? They are made of stainless so, they won't be rusty but, really? Bound to have a couple scuffs and scratches you're going to introduce to your shiny new car. All to save a lousy $200?
These things will be stupid loud and drone like hell, too but, that's a matter of personal taste.
