Go with the one from UnlimitedTuning. It's more of an M style lip.
Here is mine:

 

Gizmos 35,

I swear I had read in another thread somewhere where they said the real impul was only $120 more than the replica. And I even went to the site to check it out, cuz they had both spoilers on it. Stupid me I forgot to save the site, I tried searching for the thread again, but no luck. Perhaps I was drooling over this spoiler so much that I dreamt that the whole thing. Anyways, there is no way I am willing to shell out 450 for that spoiler.

Moog, Thanks for the pix. love dem wheels...

 

Unfortunately Impul is not a high discount company. Expect to pay over $400 for the real spoiler
