Well a Boss Shinoda has Stages or Models like all speciality stangs.... Stage 1 basic catback stickers, lowerin springs... Stage II the same but with gears, caster cambers and shocks also, Stage 3 Twin Turbo...
Mine is a Boss Legacy... Which long story short is the sticker and body package. Because I allready had some mods done and wanted to do my own modification route, but by making it a legacy it is still certified as long as I keep the look no matter which mods or brands or w/e I use.
