An exhaust place has 16ga exhaust pipe that he claims is exactly 2" OD. Only thing is, it's gonna rust over time. Wonder how would it be to paint?
This is so dumb that DirecTV didn't use a standard size. I may call them and demand a relocation of my dish. I've been with them for almost 10 years and think that's the least they could do to keep me happy. Just trying to be proactive for next winter is all.
You can get stainless steel exhaust pipe. It's not cheap, but it won't rust!
