ask and it shall be given unto you.
Here are a couple pics I took. The first shows the subframe is about 3 3/4" off the ground. The camera is angled up a bit and the headers look like they hang lower than they do. The second pic shows actual header to frame rail relationship. I'm too old and busted up to crawl under and get a measurement at the collector but it's maybe around 3 1/2"? That's pretty decent considering how low the car is.
