Exhaust System for O-320/360

[Yellow Baron]

O-320/360 original exhaust system. System was originally on my O-320, and was subsequently fitted to my O-360 which was easy given the slip joints. TT is 2600, I flew it for about 10 years/~600 hours, I took it off to upgrade to a Leading Edge system. The shroud is pretty new and in good shape it was replaced at 1963 TT so it has only ~600 hrs on it. Welded a crack on the carb-heat heat exchanger and muffler about 400 hours ago but it was all tight and airworthy when taking it off Oct '11.

Any idea what this is still worth?
