Is there a thread on the exhaust weights? My search came up dry.
Someone must have removed them and commented on them by now?
I know my car has at least four of them on there, I was wondering if there was a problem with vibration or something if you took them off?

Well I removed the weights and replaced them with Borla ATAK axle backs. I was amazed at the weight difference between the factory and Borla exhaust. I know that isn't exactly what you were talking about but the factory exhaust is just heavy even without the weights on it.

I think he's asking about the little cylindrical dampeners that are bolted to the exhaust at the x pipe and on each muffler.
I mentioned them in my axle back install post, but the thread is so old it may have been pruned from the server.
Anyhow, they are little dampening masses that keep the stock pipes from resonating and the interior quiet. When I put MRT exhaust on my car I took the dampers off the stock mufflers and attached them to the clamps since the MRT set had so much cab drone. It helped some.
I have since switched to the mufflers from Corsa. No drone and plenty loud although they don't have the "sweetness" of tone the MRTs did. But no need for the dampeners.
Ford probably made the stock exhaust heavier just because they wanted it to last. Drive your Mustang through a couple of winters up here in Michigan and I bet your light weight aftermarket exhaust will be rotting off the car, unless you bought the stainless exhaust.

I was talking to a Ford Mechanic, he was telling me the weights are just to cut down on vibration.
But as for the other comments, you guys were mentioning stuff that has been on my mind. I really would like to know how much weight you can shave off by swapping out the exhaust. Of course I live in Kalifornia where there is a limit to how much you can do and pass inspection. I know I was reading some posts and people were talking about how hard it is to change out the exhaust in front of the axle with out a lift so that is another limitation.
I guess I wish exhaust information was a little more available and a little more scientific. I know most people shop based on sound, but I want to be able to figure out what will work best with my set up.
I will have to look for that spread sheet on AFM, that is a good start.
