will it work?

Was looking into the slp c/b system, but my lx is a 90 and they dont make em for the fox (start at 94 and up). Was told that mabye the only difference though in the exhaust from 87-93, to 94-97 is hanger type and location. If this is true i could swing it with minimal mods. Does anyone know for sure if in fact they are the same except for the hangers?
