you know what piece im talkin about?It goes on the bumper.Can I buy replacements cuz when I first got the car my brother pulled it off cuz he said it looked like crap,now it looks like crap cuz it aint on there no more.Where can I get it if I even can?

 

that mess is like hell to replace you gotta take off the whole bumper get it from the factory with unbroken clips its bad news you can try spraypainting it
with the color of your car...

 

take some body filler and fill it in...sand and paint.

just keep in mind its most likely to only last a few years before it cracks

 

Or don't bother at all.

 

It all depends on your tastes, but they sell plastic bumper protector in rolls, all have double sided tape. They come in different widths at pepboys
