Re: Is this normal from factory
No problems caused. If you do a search on this forum for exhaust crimp you will find several previous posts/threads with pictures involving the MY14s when they first came out particularly the SRTs. You can read about how it was getting noticed by other owners why it's supposedly there and how some chose to address the crimp.
