I live as far upstate NY as you can. The roads are salted so bad you cant even see the pavement and my muffler looks actually really good lol. I could take some pics if you want. There is some surface rust but it seems to be in pretty darn good shape. I have had it for like 2-3 years.

Hmm..maybe I can coat it with some rust protection somehow? The entire underside of my car is undercoated .......
