what a price! are you going to do anything to it before installing?i just bought a fresh cooled one for $800 but they typically go for the 1 to 2 k region
depending on what is included and optional upgrades
I would avoid galvanized exhaust as the coating burns off quickly and produces noxious fumesthere are a few threads on here regarding the black pipe and galvanised exhaust solutions...
quite budget and long lasting
