I like the 2" exhaust. It works great since I have a airtight drum now. I use a tin can to put over the exhaust to slow it down before turning the meat and to shut it down after the cook.
Not quite sure what your pic shows, maybe another one later will help. Good luck with the build.
Barbarian, that is one awesome looking UDS, you may have to drop the U ! Hope you don't mind I am going to try to clone it! I will change up the paint scheme for sake of identity. Both drums I have are closed drums, was yours an open ended??
