Yeah, the time those were on the car I lived in rust belt. Ohio.

Chad...there was some slight creaking/squeaking noises when I drove over small bumps. BUT...when I was doing the install I also was messing with other stuff and I was swinging my exhaust around a bit and had some of the same noise, so I lubed the hangers which pretty much stopped it. So after the install the noise went away, but I can't for sure say it was the exhaust or the joints or a combination of both.
