Chin spoiler:


Front Under spoiler:



basically, they're the same thing, but honda has two different versions (yes, I know the second pic is from a '99-'00, but Honda had them for '96-'98s also) of the same thing. The front under spoiler comes painted to your factory color, while the chin spoiler comes black. However, if you get your chin spoiler painted, then the only difference is in the shape of the design. Also, the chin spoiler just bolts right on to the bottom of the bumper and that is all it covers, whereas the front under spoiler actualy comes up and covers the lower half of the bumper (refer to pictures).
