Hi all, I have the original Thermal Reactor muffler out of my 77 GTB lying around. I have no use for it and will throw it away. Before doing this, if there is anyone in the Toronto area that wants it, they can have it. The muffler is very intact and has no rust or rot. Actually it is in very good shape (all of the shields are intact too). E-mail me: email@example.com if you want it. If there are no takers in a week, it is off the the scrap heap.
