I didn't do very much at the hangar because I didn't want my spouse to get mad because I was playing at the hangar and not at home where she was slaving away on Thanksgiving dinner. Besides, I went there to get safety wire to put up garland and wreathes.
Anyway, I attached the four exhaust tubes, and found the heat shields and clamps, the latter of which actually came with the finishing kit, it turns out.
Put the tubes on but waited until tomorrow for the muffler. I had to get back home.
