I have the Magnaflow 16633 cat-back on mine, and I will be attending woodward. But I think I'll trailer mine, sorry.
Just kidding.......actually, I'll be out there this upcoming saturday night (8-9-08) as well as the week of the cruise. I put mine on in about 4 hours, but I have the roadster, underbody brace kind of sucked. Coupes are much easier!
