The reason you originally got laughed at/flamed/whatever was the way you phrased your post about the free exhaust. I don't remember exactly what you said, but it was something to the effect of "There is a free SVT exhaust sitting behind Mike's Pizza* if anyone wants to go take it." Like I said, I don't remember exactly what you said (and I don't feel like looking for the topic) but you made it sound like you saw it and anyone could go steal it, not that YOU were giving it away. So that is probably why you got flamed. It wasn't until you clarified things in your second post that I knew you meant it was yours. Hope that helps.
