Lesson learned, loosen up all the clamps to be able to readjust everything so you don't have the issues I have had with rubbing and rattling issues. I installed a UPR OR X pipe this past week and I had the same issue. I loosened up all the clamps to readjust everything and no more issues
Cool thanks, I figured it was something like this.
I will try to re-adjust like you said but won't be able to do this for about a week because of my crazy work schedule. I still need to drive my car, hope nothing gets damaged until then. Until being fixed I'll warm it up before driving anywhere. There isn't any rubbing once warmed up.
