Here's my $35 lip wrapped in cf vinyl.

I cut a v shape in the bottom center and also tapered out the ends on the bottom to sit much more flush to the bumper. The first comment made was that it looks like an OEM fit, not aftermarket. I think tappering those ends made it flow into the sides of the car a lot better. I'm still not sure of whether or not I like it enough to keep it on there, though.
