I have a 04 Impala SS and was considering the kit? Would it be worth it? Does my car have these parts on it already?

i think the only way to tell if you already have the gmpp is to look at the code # inside the door. i forgot what's the code # was, but you probably can ask the dealer and they probably tell you.
