I've seen this on many a DC-3, especially with Wrights, where visiblie on the lower outter portion of the firewall is the cutout for the exhaust stack however it has been faired over. Can anyone explain to me why this is?

Flagship Tulsa was originally Wright-powered, but converted to Pratts sometime after AA disposed of her. I'd imagine that explains the modification to the nacelles, vernicator.

Scott,
Trans-Texas converted FST to "DC-3A" status on 4-20-49. I'd guess that's probably when the conversion took place, with some war-surplus Pratts.

Thanks, Kevin.
I think you sent me the photo of the conversion dataplate earlier, but I was too lazy to look for it last night. That date would indeed have been when the P&Ws went on, making it a DC-3A.

Actually that would be backwards. Usually the pratts have the longer stack that fist into that "nook" and the Wrights had the short stack that jutted out the side...very weird how there is such a variety of this little detail amongst the DC-3/C-47 world.

The longer exhust pipes usually have a heat exchanger built around the straight part of the pipe. The hot fresh air from the heat exchanger is ducted to the cabin and cockpit for heating.
If you have a look at the photo in the previous post above you can see the inlet pipe for the heat exchanger level with the cowl gill.
I have seen the long pipe on both P&W and wright powered DC-3's.

Jason is correct, the original installation on AA's aircraft had the long exhaust stack as shown on this photo of Flagship San Francisco. Flagship Knoxville, in the AA Museum at Fort Worth, has Wright engines and the long stacks identical to these:
Flagship Detroit had the short stacks installed at some time in the past.
