Which car do you have? Such a setup might work OK...but I can't imagine that it would pass the Calif smog-nazi visual inspection in the least! Nothing about it resembles stock on a post-74 911. If the inspector knows 911's well at all, or has good pics to look at, I think he'd be onto it in no time.
