Sorry I may have needed to be more clear. It is rubbing about half way back. The rattle is the heat shield that covers the drive shaft about where the rear passenger feet are.
The other question though is it worth wrapping the turbo back only or should I do headers back?
Will wrapping the turbo back cause heat issues in other areas of the exhaust system? Like melting my rear bumper?
Is there a legitimate reason that your warranty would be void for wrapping your headers?
