rear lip???

I have ordered a front lip for the 3dr civic but i want to get a rear one, do any fit off of other hondas or is it just the civic ?

coz i dont wanna get one from honda coz they r just a bunch of dumb ass's in the dealership near me and will cost loads anyway,

well, the SIR civic's came with one (EF9 or EF8) i dont' remember specifically
Good luck!
