Don't Roush stangs have side-exit exhaust? Could have just been a Roush kit..........

 

Stage 1 is a Stock GT with 30 lbs of body kit put on [8D]

And signatures everywhere.

To quote a part of it...
Stage 1, while being predominantly an appearance package, offers some of the optional items of the Sport package as standard features to aide in handling. Also, like the Sport package, the Stage 1 package was mostly applied to V6 models, yet this package was more popular with GT owners then was the Sport package. The standard items of the New Edge Roush Stage 1 are as follows:
