well the header blew a hole out, metal is old and very thin. was approx, the size of a nickel. Since i like the oily death plumes staying in the exhaust, we had to fix it. Plus it sounded like straight ass. Twas the night before rallyx too. Seth (pictured) ended up having to make a piece of metal to weld over top of it. The header is too thin to weld the hole without any filler piece.
