Took this off my car in favor of an authentic Vorsteiner Type I rear diffuser. Typical JL fitment which means, it's okay but not perfect. I'm anal so I needed better. Should've just bought the Authentic in the first place.
$250 ($449USD plus shipping and taxes from JL motoring).
There are some melt/burn marks where my exhaust touched the diffuser. Invisible when installed. From the outside, it looks pretty much perfect.
Thanks for looking.
