I have the zl1 bumper. Not trying to pose as a zl1, just dented my bumper and really liked the zl1 look so I went with it. The rest of my car is LT so it's pretty easy to tell it's just the bumper.
You could say my Ark N-II exhaust is posing my car as a v8 because it sounds like one and people tell me "I love the v8 sound on your camaro" all the time. Sometimes I correct them and tell them its a v6 and watch their jaw drop, other times I just smile and nod
