Last minute builds/changes before Proving Grounds on July 8th?

[scheides]

Just wondering if anyone is doing any last minute bolt-ons or full builds before the track day on July 8th? I was hoping to do a SS o2 housing, ported manifold, and test pipe, but it looks like I'll just be doing the test pipe. The o2 housings are on back-order, and since the ported manifold won't make much difference without it, I'm not going to bother swapping it in.
