Busted a small hole in my NUR Spec exhaust piping? Causes??

[AAA240SX]

I just bought a Blitz NUR Spec Cat-Back a couple of months ago. I bolted it on back in October. I drove it for about 1 month and in late November I garaged it before snow got really heavy...

Occassionaly i start it up in my garage, and once in a while drive it around my block to keep the engine in good shape.

But yesterday, I noticed that water (from condensation) was leaking from around the area of my diff. in the back. Not at the joint though, so my gasket is still good. It's a small hole...

What could have caused this happen? Salt maybe? But it's stainless steel...Does salt affect it? Any ideas can help...

either scraped it or what i did...mine stressed at the hanger welding...basically took broke the hanger off and part of the exhaust.

My car is still at stock height. That's why it's weird. I'm still using the stock rubber hangers. They don't seem to be sagging at all but could it be that?

my friend had a brand new DC sports twin can exhaust on his new civic, that thing was like 750 bucks... and there was a lil rock in the road that dented it up and put a hole in it like the first month he had it on the car.
